Ratio of pen |
4 u |
2 u |
7 u |
13 u |
Value of each pen |
$1.50 |
$0.80 |
$0.40 |
|
13 u = 416
1 u = 416 ÷ 13 = 32
Number of Pen A
= 4 x 32
= 128
Number of Pen B
= 2 x 32
= 64
Number of Pen C
= 7 x 32
= 224
Total revenue
= 128 x 1.50 + 64 x 0.80 + 224 x 0.40
= 192.00 + 51.20 + 89.60
= $332.80
Answer(s): $332.80
