Question

Martha goes to the store and spends $114 on food and $66 on non-food items. The local sales tax rate in her town is 3.3% on food items and 5.3% on non-food items. The state sales tax rate is 3.7% on food items and 5.5% on non-food items.  What is the total cost of her purchase (including taxes)?

Answer 1

The $114 in food gets taxed 3.3% and 3.7%, so the taxes on the food are

 

Local $114 * .033 = $3.762

State $114 * .037 = $4.218

 

 

The $66 on non-food items are taxed as follows:

 

Local $66 * .053 = $3.498

State $66 * .055 = $3.630

 

So all together her purchase was:

 

$114 + 3.762 + 4.218 + $66 + 3.498 + 3.630

 

=$195.108  

 

= $195.11
