5 u |
1 u |
| Total value |
35 u |
10 u |
Cost of 1 muffin = 1 u
Cost of 1 cookie = 5 u
Total cost of 7 cookies and 10 muffins
= 7 x 5 u + 10 x 1 u
= 45 u
Fraction of Nora's money left
= 1 -
911 =
211911 of Nora's money = 45 u
111 of Nora's money = 45 u ÷ 9 = 5 u
211 of Nora's money = 5 u x 2 = 10 u
Number of cookies that Nora could buy
= 10 u ÷ 5 u
= 2
