2,240 divided by 28= 80. 80 times 32= 2,560. 2,560+2,240=4800. Figure out the rest alone xD
Answer:


Step-by-step explanation:
Given

per mile
Solving (a): Linear Equation
The total charges (c(x)) is: the base charge + the rate * number of miles (x).
So, we have:


Solving (b): Cost of rent, if miles = 160
This implies that x = 160
So, we have:




Test each one out! Coordinates are written in (x, y) so just substitute each one
A) 3(1)+2(4) = 11
B) 3(2)+2(3) = 12
C) 3(3)+2(1) = 11
D) 3(4)+2(-1) = 10
Out of all these answers B has a value less than 12 so the answer is:
B (2,3)
Answer:
