Question

Samuel orders four DVDs from an online music store. Each DVD costs $10.00. He has a 20% discount code, and sale tax is 6.75%. What is the total cost of his order

Answer 1

Answer:

$34.40

Step-by-step explanation:

this equation has 3 steps

1. to find out how much the dvds cost without any discount or tax: $40

2. the price of the dvds with the 20% discount, which can be found with cross-multiplication making the price after discount $32

3. the final price of the dvds with sales tax can be found also with cross-multiplication and the final answer would be 34.4

Answer 2

Answer:

$34.7

Step-by-step explanation:

40 x 0.0675 to find the tax.

40 x 0.8 to find how much to pay

40 x 0.0675 = 2.7

40 x 0.8 = 32

32 + 2.7 = 34.7
