Ratio of crayon |
6 u |
2 u |
8 u |
16 u |
Value of each crayon |
$1.50 |
$0.80 |
$0.50 |
|
16 u = 496
1 u = 496 ÷ 16 = 31
Number of Crayon K
= 6 x 31
= 186
Number of Crayon L
= 2 x 31
= 62
Number of Crayon M
= 8 x 31
= 248
Total revenue
= 186 x 1.50 + 62 x 0.80 + 248 x 0.50
= 279.00 + 49.60 + 124.00
= $452.60
Answer(s): $452.60
