Answer:
<h2>d. $250</h2>
Step-by-step explanation:
We can use the equation of a straight line to model the cost of servicing the car.
let the cost be y and the number of hours be x
and the charge per hour is m
y=mx+c
y=50x+25
given that the time is 3.45 hours it is assumed that the charge is for 4 hours since for a fraction of 0.45 hours we are charged $50
y=50(4)+25
y=200+25
y=$225
Simply multiply 4 for the terms in the parenthesis
4x-4
There are 10 boys because half of 10 is 5 5+5 equals 10
Answer:
the equation would be b. y=2x-3.
Im not sure but I think its C
