Cupcakes |
Puffs |
| Number |
9 |
4 |
| Value |
4 u |
1 u |
| Total value |
36 u |
4 u |
Cost of 1 puff = 1 u
Cost of 1 cupcake = 4 u
Total cost of 9 cupcakes and 4 puffs
= 9 x 4 u + 4 x 1 u
= 40 u
Fraction of Diana's money left
= 1 -
211 =
911211 of Diana's money = 40 u
111 of Diana's money = 40 u ÷ 2 = 20 u
911 of Diana's money = 20 u x 9 = 180 u
Number of cupcakes that Diana could buy
= 180 u ÷ 4 u
= 45
