Step-by-step explanation:
cost =$25.50
=5%÷100=0.05

Answer:
$82
Step-by-step explanation:
If the coat is 1/3 off then you pay 2/3 of the price. To find a sale price, multiply the cost by 2/3.
123(2/3) = 246/3 = 82
The sales tax is the additional cost with a value of a fraction of the gross cost. Let's compute first the gross cost:
Gross cost = 3($1.59) + 2($3.25) = $11.27
The sales tax is, therefore, 7.25% of $11.27.
Sales Tax cost = $11.27(0.0725) = $0.817
The total purchase is equal to the gross cost and the sales tax cost.
Total Purchase Cost = $11.27 + $0.817 = $12.09
