Lynn spent
35 of her money on 7 muffins and 10 wafers. If each muffin costs twice as much as a wafer, how many wafers could Lynn buy with the rest of her money?
| |
Muffins |
Wafers |
| Number |
7 |
10 |
| Value |
2 u |
1 u |
| Total value |
14 u |
10 u |
Cost of 1 wafer = 1 u
Cost of 1 muffin = 2 u
Total cost of 7 muffins and 10 wafers
= 7 x 2 u + 10 x 1 u
= 24 u
Fraction of Lynn's money left
= 1 -
35 =
2535 of Lynn's money = 24 u
15 of Lynn's money = 24 u ÷ 3 = 8 u
25 of Lynn's money = 8 u x 2 = 16 u
Number of wafers that Lynn could buy
= 16 u ÷ 1 u
= 16
Answer(s): 16
