Ratio of pen |
6 u |
3 u |
8 u |
17 u |
Value of each pen |
$1.80 |
$0.90 |
$0.40 |
|
17 u = 476
1 u = 476 ÷ 17 = 28
Number of Pen A
= 6 x 28
= 168
Number of Pen B
= 3 x 28
= 84
Number of Pen C
= 8 x 28
= 224
Total revenue
= 168 x 1.80 + 84 x 0.90 + 224 x 0.40
= 302.40 + 75.60 + 89.60
= $467.60
Answer(s): $467.60
