Answer:

A = -12

B = -8

C = -4

Step-by-step explanation:

y=2x-8

x = -2

y=2(-2)-8=-4-8=-12

A = -12

x = 0

y = 2 (0)-8=-8

B = -8

x = 2

y = 2 (2) -8 = 4-8 = -4

C = -4

Hope this helps

#15(A)
First Bike
$380 - $190 ($380 * 0.50) = $190

2nd Bike
$380 - $114 ( $380 * 0.30) = $266
$266 - $53.20 ($266 * 0.20) = $212.80

#15 (B)
Eliza should buy the first bike because it is cheaper. $190 < $212.80

#16
$57 + $28.50 ($57 * .50) = $85.50
