Answer: The wholesale cost of the bike = $100
Step-by-step explanation:
Let x = wholesale cost of the bike
As per given,
Selling price = cost price + (Mark up percent) x ( cost price) (i)
Selling price of bike = $160
Mark up percent = 60% =0.60
Substitute values in (i) , we get

Hence, the wholesale cost of the bike = $100
Slope = rise/run
Rise = 3, run = 8
Downwards line = negative
Slope = -3/8
