$2 |
|
Total value |
4 u |
2 u + 12 |
6 u + 12 |
Amount spent on muffins
= 4 x 1 u
= 4 u
Amount spent on sandwiches
= 2 x (1 u + 6)
= 2 u + 12
Total amount spent on the pastries
= 4 u + 2 u + 12
= 6 u + 12
6 u + 12 = 36
6 u = 36 - 12
6 u = 24
1 u = 24 ÷ 6 = 4
Total number of sandwiches
= 1 u
= 4
Answer(s): 4
