Answer:
The mechanic who worked 5 hours charged $115 per hour, the one who worked 15 hours charged $120 per hour.
Step-by-step explanation:
x = rate of mechanic who worked 5 hours
y = rate of mechanic who worked 15 hours
Then
x + y = 235
5x + 15y = 2375
Just solve these 2 equations above for x and y.
x + y = 235 ⇒ x = 235 - y
Substitute into second equation to find y.
5(235 - y) + 15y = 2375
1175 - 5y + 15y = 2375
10y = 1200
y = 1200/10 = 120
x = 235 - y = 235 - 120 = 115

Answer:
See below in bold.
Step-by-step explanation:
a. The y coordinate will be (0, 25,350) as $25,350 is the value of the new car at year 0.
The x coordinate will be when the car is worth zero dollars and this is at the point (13, 0).
b. The slope = -25,350 / 13 = -1950.
c. The equation is y = -1950x + 25350.
d. To draw the graph just join the above 2 points.
