Xylia spent
911 of her money on 7 scones and 10 shortbreads. If each scone costs five times as much as a shortbread, how many scones could Xylia buy with the rest of her money?

| Number |
7 |
10 |
| Value |
5 u |
1 u |
| Total value |
35 u |
10 u |
Cost of 1 shortbread = 1 u
Cost of 1 scone = 5 u
Total cost of 7 scones and 10 shortbreads
= 7 x 5 u + 10 x 1 u
= 45 u
Fraction of Xylia's money left
= 1 -
911 =
211911 of Xylia's money = 45 u
111 of Xylia's money = 45 u ÷ 9 = 5 u
211 of Xylia's money = 5 u x 2 = 10 u
Number of scones that Xylia could buy
= 10 u ÷ 5 u
= 2
Answer(s): 2
