The question is find the total cost when the price is $89.75 and the tax is 7 1/4%

Total cost = price + tax

Tax  = 7  1/4 % of price

Tax rate = [7 + 1/4] = 7.25 %

Tax = 7.25 % * price = 7.25 % * $89.75 = $[7.25/100] * 89.75 = $6.51

Total cost = $89.75 + $ 6.51 = $96.26

For this case, the first thing we must do is find the amount of taxes.

For this, we make the following rule of three:

89.75 ----------------------> 100%

x ----------------------------> 7 1/4%

From here, we clear the value of x.

We have then:

\(x = (\frac{7\frac{1}{4}}{100}) * (89.75)  x = 6.51\)

Then, the total cost is given by:

\(Total Cost = price + taxes\)

Substituting values:

\(Total Cost = 89.75 + 6.51  Total Cost = 96.26\)

Answer:

The total cost is equal to 96.26 $.
