Answer:
a. 61.25
b. 70
c. 212
Step-by-step explanation:
a. What is your cost if you travel 57 miles?
The cost is $ .
y=47+0.25x
y=47+0.25(57)
y=47+14.25
answer: 61.25
b. If your cost was $64.50, how many miles were you charged for traveling?
You were charged for traveling miles.
64.50-47=0.25x
17.50=1/4x
17.50*4
answer 70=x
c. Suppose you have a maximum of $100 to spend for the car rental. What would be the maximum number of miles you could travel?
The maximum number of miles you could travel is miles.
100-47
53=1/4x
answer : x= 212
785.63-(57+125)
=785.63-182
=603.63
603.63+57.25=$660.87
Am assuming the text of the problem is:
"At 6:00 p.m., the temperature was 55 Fahrenheit. At 11:00 p.m. that same evening, the temperature was 40 Fahrenheit. What real number represents the average change in temperature per hour?"
Average change in temperature per hour = (55 - 40)/(11 - 6)
Average change in temperature per hour = 15/5
Average change in temperature per hour = 3 Fahrenheit per hour
