A pair of shoes usally sells for $68. If the shoes are 20% off, and sales tax is 7%, what is the total price of the shoes, including tax?

$50.59

Step-by-step explanation:

First you take off 20% from 68. ( 68 * 0.2 = 13.6 )

68- 13.6 is 54.4

for the sales tax, you take out 7% of 54.4

54.4 * 0.07 = 3.808

54.4-3.808 = 50.59!

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
