Sonbull [250]

Based on the cost of the calculator, the discount, the shipping fee, and the tax, the total cost of the purchase was<u> a. $80.07</u>

<em>= Cost of calculator x ( 1  - discount)</em>

= 83 x ( 1 - 15%)

= $70.55

The sales tax would be:

= 70.55 x 4.5%

= $3.17

The total cost would be:

<em>= Cost + Sales tax + Shipping fee</em>

= 70.55 + 3.17 + 6.35

= $80.07

In conclusion, the total is $80.07.
