Winnie spent
811 of her money on 5 shortbreads and 6 tarts. If each shortbread costs twice as much as a tart, how many tarts could Winnie buy with the rest of her money?

Shortbreads |
Tarts |
| Number |
5 |
6 |
| Value |
2 u |
1 u |
| Total value |
10 u |
6 u |
Cost of 1 tart = 1 u
Cost of 1 shortbread = 2 u
Total cost of 5 shortbreads and 6 tarts
= 5 x 2 u + 6 x 1 u
= 16 u
Fraction of Winnie's money left
= 1 -
811 =
311811 of Winnie's money = 16 u
111 of Winnie's money = 16 u ÷ 8 = 2 u
311 of Winnie's money = 2 u x 3 = 6 u
Number of tarts that Winnie could buy
= 6 u ÷ 1 u
= 6
Answer(s): 6
