Ratio of pencil |
6 u |

8 u |
16 u |
Value of each pencil |
$1.40 |
$0.90 |
$0.60 |
|
16 u = 432
1 u = 432 ÷ 16 = 27
Number of Pencil F
= 6 x 27
= 162
Number of Pencil G
= 2 x 27
= 54
Number of Pencil H
= 8 x 27
= 216
Total revenue
= 162 x 1.40 + 54 x 0.90 + 216 x 0.60
= 226.80 + 48.60 + 129.60
= $405.00
Answer(s): $405.00
