The cost of the wool hats at their full price will be $28
Since the wool hats are selling for $4 less than full price and Jeffrey pays a
total of $120 for the 5 hats, this can be represented by the equation:
5(x - 4) = 120
5x - 20 = 120
Collect like terms
5x = 120 + 20
5x = 140
Divide both side by 5
5x/5 = 140/5
x = 28
Therefore, we've solved that the cost of the wool hats at their full price will then be $28. This means Jeffrey paid $24 for each since $4 was deducted.
