Ratio of pen |
6 u |
3 u |
8 u |
17 u |
Value of each pen |
$1.50 |
$0.80 |
$0.60 |
|
17 u = 425
1 u = 425 ÷ 17 = 25
Number of Pen F
= 6 x 25
= 150
Number of Pen G
= 3 x 25
= 75
Number of Pen H
= 8 x 25
= 200
Total revenue
= 150 x 1.50 + 75 x 0.80 + 200 x 0.60
= 225.00 + 60.00 + 120.00
= $405.00
Answer(s): $405.00
