Answer:
$33600
Step-by-step explanation:
Let x = original car price
Since it is a 25% profit that means we multiply x by 1.25
1.25x = 42000
Divide both sides by 1.25
1.25x/1.25 = 42000/1.25
x = 33600
x= 20.05 degree
180= 43.25+36.50+5x
180= 79.75+5x
5x=180-79.75
5x=100.25
x=20.25
ANGLE B= 100.25
7,13,37,55,103
y = 5 + 2x^2
if x =1
y = 5 + 2(1)^2
1^2 = 1
2 x 1 = 2
y=5 + 2 or y = 7
you substatute each one in for x to solve for y
