Tarts |
Macarons |
| Number |
3 |
9 |
| Value |
5 u |
1 u |
| Total value |
15 u |
9 u |
Cost of 1 macaron = 1 u
Cost of 1 tart = 5 u
Total cost of 3 tarts and 9 macarons
= 3 x 5 u + 9 x 1 u
= 24 u
Fraction of Diana's money left
= 1 -
611 =
511611 of Diana's money = 24 u
111 of Diana's money = 24 u ÷ 6 = 4 u
511 of Diana's money = 4 u x 5 = 20 u
Number of macarons that Diana could buy
= 20 u ÷ 1 u
= 20
Answer(s): 20
