Answer:
$26.32
step-by-step explanation:
it originally was $40.00
she has a coupon for 30%
30% of 40.00 is 12
40 • 0.30 = 12
40 - 12
$28
it is now $28 after the coupon
her state charges an 6% sales tax on the discounted price
6% of 28 is 1.68
28 • 0.06 = 1.68
28 - 1.68 = 26.32
x+y=12
x-y=4
Then you solve:
x+y=12
-y -y
x=12-y
x-y=4
+y +y
x=4+y
4+y=12-y
+y +y
4+2y=12
-4 -4
2y=8
divide both sides by 2 to isolate y
y=4
Plug it into one of the equations
x+4=12
-4 -4
x=8
