1 u |
| Total value |
12 u |
4 u |
Cost of 1 scone = 1 u
Cost of 1 puff = 4 u
Total cost of 3 puffs and 4 scones
= 3 x 4 u + 4 x 1 u
= 16 u
Fraction of Fiona's money left
= 1 -
29 =
7929 of Fiona's money = 16 u
19 of Fiona's money = 16 u ÷ 2 = 8 u
79 of Fiona's money = 8 u x 7 = 56 u
Number of scones that Fiona could buy
= 56 u ÷ 1 u
= 56
Answer(s): 56
