Anna spent
59 of her money on 7 biscuits and 6 muffins. If each biscuit costs twice as much as a muffin, how many biscuits could Anna buy with the rest of her money?
| |
Biscuits |
Muffins |
| Number |
7 |
6 |
| Value |
2 u |
1 u |
| Total value |
14 u |
6 u |
Cost of 1 muffin = 1 u
Cost of 1 biscuit = 2 u
Total cost of 7 biscuits and 6 muffins
= 7 x 2 u + 6 x 1 u
= 20 u
Fraction of Anna's money left
= 1 -
59 =
4959 of Anna's money = 20 u
19 of Anna's money = 20 u ÷ 5 = 4 u
49 of Anna's money = 4 u x 4 = 16 u
Number of biscuits that Anna could buy
= 16 u ÷ 2 u
= 8
Answer(s): 8
