use c = 35h + p to find the cost (c) of having a car tuned up if the charges are $35 per hour(h) for labor plus the cost of parts (p). The mechanic estimates it will require 2 hours of labor and $75 for parts
a) $220
b) $110
c) $145
d) $35
c = 35h + p
c = (35 * 2) + 75
c = 70 + 75
c = ?
c = 145
To find the cost (c) of having a car tuned up, we can substitute the given values into the equation c = 35h + p.
Given:
h = 2 hours
p = $75
Substituting these values into the equation, we get:
c = 35(2) + 75
Now, we can simplify the equation:
c = 70 + 75
Add the numbers:
c = 145
Therefore, the cost (c) of having a car tuned up is $145.
So, the correct answer is option c) $145.
