Question

If I buy a box of nails that was worth 14.99 and I have a coupon for 20% off and the sales tax is 6% how do I get the total cost

Answer 1

Given

Cost = 14.99

Discount = 20% off

Sales tax = 6%

We want to find the total cost

Solution

Discount (D)

$\begin{gathered} D=\frac{20}{100}\times14.99 \\ D=2.998 \end{gathered}$

The price after the discount is

$14.99-2.998=11.992$

The sales tax (t)

$t=\frac{6}{100}\times11.992=0.71952$

Therefore, the total cost (T) will be

$\begin{gathered} T=11.992+0.71952 \\ T=12.71152 \end{gathered}$

Thus, the total cost is 12.71152

Total cost = 12.71 (to 2 decimal places)
