Ratio of marker |
5 u |
3 u |
8 u |
16 u |
Value of each marker |
$1.10 |
$0.70 |
$0.50 |
|
16 u = 400
1 u = 400 ÷ 16 = 25
Number of Marker E
= 5 x 25
= 125
Number of Marker F
= 3 x 25
= 75
Number of Marker G
= 8 x 25
= 200
Total revenue
= 125 x 1.10 + 75 x 0.70 + 200 x 0.50
= 137.50 + 52.50 + 100.00
= $290.00
Answer(s): $290.00
