$1.20 |
Total Value |
1.1 u |
3.6 u |
1.2 u |
Mocca shortbreads : Blueberry shortbreads : Cream shortbreads
1 : 2 : 1
Total amount earned from selling all the shortbreads
= 1.1 u + 3.6 u + 1.2 u
= 5.9 u
5.9 u = 295
1 u = 295 ÷ 5.9 = 50
Number of blueberry shortbreads
= 2 u
= 2 x 50
= 100
Answer(s): 100
