Question

Last year, Andrea bought 85 songs from an online company for a total of $96.90. Each song cost $1.09 plus tax.

Part A

Which equation can be used to determine the amount of tax, x, in dollars, that Andrea paid for each song?


85(1.09)+x=96.90
85 times 1 point 0 9 plus x is equal to 96 point 9 0

85x+1.09=96.9085 x plus 1 point 0 9 is equal to 96 point 9 0

85(1.09+x)=96.9085 times open paren 1 point 0 9 plus x close paren is equal to 96 point 9 0

x(85+1.09)=96.90x times open paren 85 plus 1 point 0 9 close paren is equal to 96 point 9 0

Question 2
Part B

How much tax, in dollars, did Andrea pay for each song?

Answer 1

Part B: $4.25 tax / Part A: The first Equation, 85 x 1.09 + x = 96.90

Explanation:

Part A: She bought 85 songs. The amount of songs times the amount of tax is the total amount of money she spent. X represents the number of dollars. So that's how I got my equation.

Part B explanation: 85 x 1.09 + x = 96.90

x = 4.25
