Ratio of marker |
6 u |

17 u |
Value of each marker |
$2.20 |
$0.80 |
$0.40 |
|
17 u = 476
1 u = 476 ÷ 17 = 28
Number of Marker K
= 6 x 28
= 168
Number of Marker L
= 2 x 28
= 56
Number of Marker M
= 9 x 28
= 252
Total revenue
= 168 x 2.20 + 56 x 0.80 + 252 x 0.40
= 369.60 + 44.80 + 100.80
= $515.20
Answer(s): $515.20
