X + y + z = 32 * 3
27 + 27 + x = 96
X = 54
2x = 108
Average of x and 2x = (54+108) / 2 = 164 / 2 = 82
Average of X and 2X = 82
N=25 because 20 divided by 4 is 5 which is 1/5 of n meaning 5x5 is 25
We are given the current market price that is <span>$1,200 and we are asked in the problem to compute the target cost if one wishes to gain a 30% profit. In this case, we have to minimize the cost to achieve the profit desired. Then,
1.3 y = 1200
where y is the target cost
y = $923.08
</span>
The difference in pay per class is 3, so to even out with he 96, you’d have to take 32 classes, the profit begins at the 33rd
Hope this helps
