Ratio of pencil |
4 u |
3 u |
7 u |
14 u |
Value of each pencil |
$1.80 |
$0.80 |
$0.40 |
|
14 u = 434
1 u = 434 ÷ 14 = 31
Number of Pencil F
= 4 x 31
= 124
Number of Pencil G
= 3 x 31
= 93
Number of Pencil H
= 7 x 31
= 217
Total revenue
= 124 x 1.80 + 93 x 0.80 + 217 x 0.40
= 223.20 + 74.40 + 86.80
= $384.40
Answer(s): $384.40
