| Chocolate | Blueberry | |
| At first | 4u + 48 | 4u |
| Sold | ¼ × (4u + 48) = u + 12 | ½ × 4u = 2u |
| Remaining | 3u + 36 | 2u |
Given: Remaining total = 211
3u + 36 + 2u = 211
5u = 175
u = 35
(a) Total cupcakes sold -> u + 12 + 2u = 3u + 12 = 117
(b) Chocolate cupcakes at first -> 4u + 48 = 188
