Answer: $84.24
Step-by-step explanation:
In this problem, multiply 35% times 120 in order to find the total discount, and subtract the product from 120, to find the net cost of the coat.
With the sales tax, multiply 8% times the net cost of the coat, and add the product to the net cost of the coat. This gives the total amount of money you must pay.
Step 1: Multiply 35% times 120
Turn 35% into a decimal. Simply move the decimal two places to the left, as you should do with all percents used in multiplication.
0.35 · 120 = 42
This is the product of the discount
Step 2: Subtract 42 from 120
Since 42 is the value of the discount, you need to subtract it from the original price of the coat.
120 - 42 = 78
This is the price of the discounted coat
Step 3: Multiply 8% times 78
Remember what you did in step 1? Just do the same math you did previously.
.08 · 78 = 6.24
This is the amount of the sales tax
Step 4: Add 6.24 to 78
Since sales tax increases the price paid, you need to add it to the price of the discounted coat.
78 + 6.24 = $84.24
This is the amount of money you must pay
