Jen spent
411 of her money on 5 biscuits and 6 macarons. If each biscuit costs twice as much as a macaron, how many biscuits could Jen buy with the rest of her money?

Biscuits |
Macarons |
| Number |
5 |
6 |
| Value |
2 u |
1 u |
| Total value |
10 u |
6 u |
Cost of 1 macaron = 1 u
Cost of 1 biscuit = 2 u
Total cost of 5 biscuits and 6 macarons
= 5 x 2 u + 6 x 1 u
= 16 u
Fraction of Jen's money left
= 1 -
411 =
711411 of Jen's money = 16 u
111 of Jen's money = 16 u ÷ 4 = 4 u
711 of Jen's money = 4 u x 7 = 28 u
Number of biscuits that Jen could buy
= 28 u ÷ 2 u
= 14
Answer(s): 14
