x= price of camera

Multiplying the price of the camera by the sales tax percent will equal the amount of tax. Add the amount of tax to the price of the camera.

x + (x * 7%)= $45.00
convert % to decimal (7% ÷ 100)

x + (x * 0.07)= 45.00
multiply in parentheses

x + 0.07x= 45.00
combine like terms

1.07x= 45.00
divide both sides by 1.07

x= $42.056

x= $42.06 rounded


ANSWER: (D) x + 0.07x= $45; x= $42.06

Hope this helps! :)
