Ratio of pencil |
4 u |
3 u |
9 u |
16 u |
Value of each pencil |
$1.50 |
$0.80 |
$0.60 |
|
16 u = 560
1 u = 560 ÷ 16 = 35
Number of Pencil J
= 4 x 35
= 140
Number of Pencil K
= 3 x 35
= 105
Number of Pencil L
= 9 x 35
= 315
Total revenue
= 140 x 1.50 + 105 x 0.80 + 315 x 0.60
= 210.00 + 84.00 + 189.00
= $483.00
Answer(s): $483.00
