Opus 4.6 4th grade homework reasoning, with Python

Let me analyze the pictograph worksheet.
Notepads (full = 50, half = 25):

Shop A: 3 full = 150
Shop B: 2 full = 100
Shop C: 4 full + 1 half = 225
Shop D: 3 full + 1 half = 175

Wait, let me look more carefully.
Shop A notepads: 3 images - they look like 2 full and 1 half? Or 3 full? Let me re-examine.
Actually, looking at the image more carefully:

Shop A: 3 notepad icons.

I'm having trouble distinguishing which icons are fully filled versus half-filled, so I'm reconsidering whether Shop A has 3 full notepads or 2 full and 1 half. The same uncertainty applies to the other shops—I need to be more careful about whether the last icon in each row is a complete symbol or a half symbol. Let me reconsider the totals for Shops C and D as well, since those might be 5 full and 3 full respectively instead of including half symbols. Looking at the image more carefully, Shop A appears to have 2 full notepads plus 1 half notepad, which equals 125 total. I'm working through the other shops' counts now—Shop B looks like 2 full notepads at 100, and Shop C seems to have around 4 or 5 notepad images that would total around 225 if it's 4 full plus 1 half.
For the pencils, I need to figure out which are large (20 each) and which are small (10 each). Shop A's pencils appear to be small ones totaling around 30, while Shop C looks like it has larger pencils that would be around 60. I'm still trying to pin down the exact counts for Shops B and D to see which shop has matching numbers of notepads and pencils. I'm second-guessing my pencil counts—let me look more carefully at the image to distinguish between the large and small ones. Shop A might have 2 large and 1 small pencil instead, which would give 50 total, or perhaps a different combination altogether that I'm not seeing clearly.
For question 6, I need to find a shop where the notepad value equals the pencil value, but the scale seems off since pencils are worth much less per unit than notepads. Let me reconsider whether I'm reading the notepad counts correctly—maybe they're smaller than I initially thought, or I'm miscounting the items in each shop.
Actually, the most straightforward approach is to carefully re-examine the pictograph itself rather than guessing. Looking at the notepad row again with the key showing full = 50 and half = 25: Shop A has 3 icons with the last one appearing smaller, so that's 125 total. Shop B appears to have 2 full icons at 100. Shop C has 5 icons...
Continuing through the pictograph, Shop C shows 4 full notepads plus a half one for 225 total, and Shop D has 3 full plus a half for 175. That confirms Shop A sold 125, and the difference between Shop C and Shop A is 100. Now moving to the pencils section where the key shows full = 20 and half = 10: Shop A has about 3 half-sized pencils totaling 30, Shop B appears to have mostly large pencils around 110, Shop C shows 3 large pencils at 60, and Shop D has 4 large pencils with one appearing smaller.
Finishing the pencil count for Shop D at 70, the total across all shops comes to 270. But when I check which shop has the same number of notepads and pencils, nothing matches up. Let me reconsider the pencil counts more carefully by looking at the image again—Shop A's pencils look small, Shop B might be 4 large and 2 small instead of 5 and 1, and Shops C and D could have different combinations than I initially counted.
If Shop B has 100 pencils and 100 notepads, that would solve Q6. Let me verify: 4 large pencils plus 2 small ones equals 100, and 2 full notepads also equals 100. That works. So my revised counts are Shop A at 30 pencils, Shop B at 100, Shop C at 60, and Shop D at 70, giving a total of 260 instead of 270.
Wait, I'm second-guessing Shop D's pencil count from the image—it could be 4 large pencils for 80, or maybe 2 large plus 2 small for 60. Let me reconsider the combinations. If Shop D is actually 60 pencils instead of 70, then my total would be 250. I'm also reconsidering Shop C: it might be 2 large plus 1 small for 50 rather than 3 large for 60, which would still give me 250 total.
I think I should write out a Python program to test my best interpretation of the image. For the notepads, I'm reading Shop A as 2 full plus 1 half for 125, Shop B as 2 full for 100, and Shop C as 4 full plus 1 half for 225.
Now I'm adding Shop D's notepads as 3 full plus 1 half for 175, and confirming my pencil counts across all shops. Let me verify that Shop B matches the constraint of having equal notepads and pencils at 100 each, then I'll calculate all the answers and write the program.
