This year, perez’s ski shop had a profit of $80,000. this is 250 percent of last year’s profit. what was the profit of perez’s ski shop last year?

So this year profit is 250% or 2.5 times greater than the profit the shop had last year.

Let x be the profit the shop had last year. To get this years profit, or 80000 $, we need to increase last years profit by 2.5 or:

2.5*x=80000. 

Solve for x:

x=80000/2.5=32000

So last year profit was 32000 $.

The surface area would be 576 because you multiply all the numbers then multiply that number by 6
