Answer:
$24.64
Step-by-step explanation:
30% off is equal to multiplying by 0.7
(32*0.7)*1.1
Sales tax increases the price and so you multiply by 1.1 (equal to increasing 10%)
32*0.7*1.1=24.64

The inverse of the equation would be solving for x, so the answer is..
the square root of y-2 with 3 as the index, and the whole equation divided by 7 the equaled to x.
X = plan A and y = plan B
7x + 9y = 720
5x + 3y = 360.....multiply by -3
---------------
7x + 9y = 720
-15x - 9y = -1080 (result of multiplying by -3)
---------------add
-8x = - 360
x = -360/-8
x = 45 minutes <== plan A
5x + 3y = 360
5(45) + 3y = 360
225 + 3y = 360
3y = 360 - 225
3y = 135
y = 135/3
y = 45 minutes <== plan B
so both plans last 45 minutes <==
