2 u |
1 u |
Cost of 1 shortbreads |
$1.80 |
$1.10 |
$1.30 |
Total Value |
1.8 u |
2.2 u |
1.3 u |
Pandan shortbreads : Mocca shortbreads : Durian shortbreads
1 : 2 : 1
Total amount earned from selling all the shortbreads
= 1.8 u + 2.2 u + 1.3 u
= 5.3 u
5.3 u = 212
1 u = 212 ÷ 5.3 = 40
Number of mocca shortbreads
= 2 u
= 2 x 40
= 80
Answer(s): 80
