Ratio of pencil |
4 u |
2 u |
8 u |
14 u |
Value of each pencil |
$2.15 |
$0.70 |
$0.60 |
|
14 u = 476
1 u = 476 ÷ 14 = 34
Number of Pencil B
= 4 x 34
= 136
Number of Pencil C
= 2 x 34
= 68
Number of Pencil D
= 8 x 34
= 272
Total revenue
= 136 x 2.15 + 68 x 0.70 + 272 x 0.60
= 292.40 + 47.60 + 163.20
= $503.20
Answer(s): $503.20
