8 |
| Value |
2 u |
1 u |
| Total value |
8 u |
8 u |
Cost of 1 muffin = 1 u
Cost of 1 biscuit = 2 u
Total cost of 4 biscuits and 8 muffins
= 4 x 2 u + 8 x 1 u
= 16 u
Fraction of Gem's money left
= 1 -
27 =
5727 of Gem's money = 16 u
17 of Gem's money = 16 u ÷ 2 = 8 u
57 of Gem's money = 8 u x 5 = 40 u
Number of muffins that Gem could buy
= 40 u ÷ 1 u
= 40
Answer(s): 40
