Respuesta :
x=number of miles.
We have the following inequation:
0.4x+94≤130
We solve the inequality:
0.4x≤130-94
0.4x≤36
x≤36/0.4
x≤90
Answer: the maximum distance will be 90 miles

Answer: the maximum distance will be 90 miles
Kent can drive the car for up to 90 miles
The given parameters are:
[tex]Rental = \$94[/tex]
[tex]Rate = \$0.40[/tex] per mile
So, the linear equation that represents the charge (y) for x miles is:
[tex]y = Rental + Rate \times x[/tex]
So, we have:
[tex]y = 94 + 0.4\times x[/tex]
Multiply 0.4 and x
[tex]y = 94 + 0.4x[/tex]
He wants to pay no more than $130, so the linear equation becomes the following linear inequality
[tex]94 + 0.4x \le 130[/tex]
Subtract 94 from both sides
[tex]0.4x \le 36[/tex]
Divide both sides by 0.4
[tex]x \le 90[/tex]
Hence, Kent can drive the car for up to 90 miles
