Muffins |
Cookies |
| Number |
4 |
8 |
| Value |
3 u |
1 u |
| Total value |
12 u |
8 u |
Cost of 1 cookie = 1 u
Cost of 1 muffin = 3 u
Total cost of 4 muffins and 8 cookies
= 4 x 3 u + 8 x 1 u
= 20 u
Fraction of Hilda's money left
= 1 -
58 =
3858 of Hilda's money = 20 u
18 of Hilda's money = 20 u ÷ 5 = 4 u
38 of Hilda's money = 4 u x 3 = 12 u
Number of muffins that Hilda could buy
= 12 u ÷ 3 u
= 4
Answer(s): 4
