Cost of 1 wafers |

$1.80 |
Total Value |
1.6 u |
7 u |
1.8 u |
Cream wafers : Strawberry wafers : Mocca wafers
1 : 5 : 1
Total amount earned from selling all the wafers
= 1.6 u + 7 u + 1.8 u
= 10.4 u
10.4 u = 260
1 u = 260 ÷ 10.4 = 25
Number of strawberry wafers
= 5 u
= 5 x 25
= 125
Answer(s): 125
