Ratio of crayon |
6 u |

9 u |
18 u |
Value of each crayon |
$1.90 |
$0.90 |
$0.30 |
|
18 u = 468
1 u = 468 ÷ 18 = 26
Number of Crayon Z
= 6 x 26
= 156
Number of Crayon A
= 3 x 26
= 78
Number of Crayon B
= 9 x 26
= 234
Total revenue
= 156 x 1.90 + 78 x 0.90 + 234 x 0.30
= 296.40 + 70.20 + 70.20
= $436.80
Answer(s): $436.80
