The original cost of the bathing suit without tax or the discount is $38.72.
Discount
The term "discount" refers to a pricing scheme in which a commodity's (goods or services) price is lower than its marked price. Simply said, a discount is a proportion of the advertised price.
How to find the original cost?
The bathing suit is 40%off including 7% tax.This means that the discount of 40% includes the tax of 7%.Thus the discount without tax will be calculated by: 40%-7%=33%
Now we will calculate the discount without tax on the final cost of the bathing suit, i.e, 33% of the final cost.
[tex]\frac{33}{100} \times 57.78=19.06[/tex]
So, we get a discount of $19.06 on the final cost.Then the original cost of the bathing suit without the tax or the discount will be the final cost less than the discount: $57.78-$19.06=$38.72
So, the original cost of the bathing suit without tax or the discount is $38.72.
