| Value |
4 u |
1 u |
| Total value |
28 u |
8 u |
Cost of 1 biscuit = 1 u
Cost of 1 scone = 4 u
Total cost of 7 scones and 8 biscuits
= 7 x 4 u + 8 x 1 u
= 36 u
Fraction of Rachel's money left
= 1 -
911 =
211911 of Rachel's money = 36 u
111 of Rachel's money = 36 u ÷ 9 = 4 u
211 of Rachel's money = 4 u x 2 = 8 u
Number of scones that Rachel could buy
= 8 u ÷ 4 u
= 2
