the original price of the workout tops is $18.95
Let's say that the original price is x, we know that the tops are on sale for $6.00 off the original price, so if Yazmin buys 4 of these, the cost will be:
C(x) = (x - $6.00)*4
And we know that the cost is $51.80, replacing that we get:
$51.80 = (x - $6.00)*4
Now we need to solve this linear equation for x.
$51.80/4 = x - $6.00
$51.80/4 + $6.00 = x = $18.95
We conclude that the original price of the workout tops is $18.95
