If the sales 5 years ago were $25,000, then we can calculate this year's sales as follows:
Calculate the percentage increase from 5 years ago to this year:
Percentage increase = 180% - 100% = 80%
Calculate the amount of increase in sales:
Amount of increase = Percentage increase x Sales 5 years ago
Amount of increase = 0.8 x $25,000 = $20,000
Add the amount of increase to the sales 5 years ago to find this year's sales:
This year's sales = Sales 5 years ago + Amount of increase
This year's sales = $25,000 + $20,000 = $45,000
Therefore, this year's sales for the art supply company were $45,000.
