First you would try to get the y variable by itself which you can do by subtracing 1/2x on both side. The equation would be y=-1/2x-15. You would then plug this into your graphing calculator and get the answer. If you do not have one, the x-intercept would be (0,-15) and the y-intercept would be (-30,0)

So first you would divide the 9 on both sides then 6 divided by 9 would be .6 repeating so m=.6 repeating.

Answer:

a. Savings =  \$16

b. Price = \$96

Step-by-step explanation:

Solving (a):

Savings = 20\% * \$80

Coupon = 20\%

Required

Determine the price before tax

First, we need to determine her savings

Savings = Coupon * Price

Savings = 20\% * \$120

Savings =  \$24

The price before tax is calculated as follows:

Price = \$120 - \$24

Price = \$96
