Answer:
The wholesale cost is $489
Step-by-step explanation:
The merchant increases the wholetag cost by 15%
The price after the increase is $562.35
This can also be seen as 115% of the wholesale cost
so,
115% of x = $562.35
Where x is the wholesale we are required to determine.
1.15x = 562.35
x = 562.35/1.15
= 489
The wholesale cost is $489
