Gwen spent
411 of her money on 6 macarons and 8 biscuits. If each macaron costs twice as much as a biscuit, how many biscuits could Gwen buy with the rest of her money?
| |
Macarons |
Biscuits |
| Number |
6 |
8 |
| Value |
2 u |
1 u |
| Total value |
12 u |
8 u |
Cost of 1 biscuit = 1 u
Cost of 1 macaron = 2 u
Total cost of 6 macarons and 8 biscuits
= 6 x 2 u + 8 x 1 u
= 20 u
Fraction of Gwen's money left
= 1 -
411 =
711411 of Gwen's money = 20 u
111 of Gwen's money = 20 u ÷ 4 = 5 u
711 of Gwen's money = 5 u x 7 = 35 u
Number of biscuits that Gwen could buy
= 35 u ÷ 1 u
= 35
Answer(s): 35
