this is for question 3 if she purchased 2 pairs of shoes at $50 each then thats $100 for both then adding $30.00 for the dress and $20.00 for the pair of trousers your total WITHOUT sales tax is $150.00
to calculate sales tax you would multiply 4% with 150 (your total sales equaling 6
(0.04 x150=6)
lastly add 6 (your calculated sales tax) to your total sale price
getting a final answer of $156.00
