Ratio of marker |
4 u |
2 u |
7 u |
13 u |
Value of each marker |
$1.10 |
$0.80 |
$0.30 |
|
13 u = 416
1 u = 416 ÷ 13 = 32
Number of Marker Z
= 4 x 32
= 128
Number of Marker A
= 2 x 32
= 64
Number of Marker B
= 7 x 32
= 224
Total revenue
= 128 x 1.10 + 64 x 0.80 + 224 x 0.30
= 140.80 + 51.20 + 67.20
= $259.20
Answer(s): $259.20
