| Number |

| Value |
4 u |
1 u |
| Total value |
20 u |
10 u |
Cost of 1 scone = 1 u
Cost of 1 cookie = 4 u
Total cost of 5 cookies and 10 scones
= 5 x 4 u + 10 x 1 u
= 30 u
Fraction of Shannon's money left
= 1 -
27 =
5727 of Shannon's money = 30 u
17 of Shannon's money = 30 u ÷ 2 = 15 u
57 of Shannon's money = 15 u x 5 = 75 u
Number of scones that Shannon could buy
= 75 u ÷ 1 u
= 75
Answer(s): 75
