1 blueberry shortbread: $1.90
1 cream shortbread: $1.40

If she collected $183 from selling all the shortbreads, how many cream shortbreads were there?

Ratio of shortbreads |
1 u |
2 u |
1 u |
Cost of 1 shortbreads |
$1.90 |
$1.40 |
$1.40 |
Total Value |
1.9 u |
2.8 u |
1.4 u |
Blueberry shortbreads : Cream shortbreads : Coffee shortbreads
1 : 2 : 1
Total amount earned from selling all the shortbreads
= 1.9 u + 2.8 u + 1.4 u
= 6.1 u
6.1 u = 183
1 u = 183 ÷ 6.1 = 30
Number of cream shortbreads
= 2 u
= 2 x 30
= 60
Answer(s): 60
