Inequality: 21d+25≤115
Jim can rent a car for maximum 4 days, therefore, he is not correct in his calculations.
Step-by-step explanation:
Given,
Per day rent = $21.00
Per mile rent = $0.10
Miles to be driven by Jim = 250
Cost of 250 miles = 250*0.10 = $25
Amount Jim can spend = $115.00
Let,
d represent the number of days.
Per day rent*number of days + cost of 250 miles ≤ Total amount to spend
21d+25≤115
Subtracting 25 from both sides
Dividing both sides by 21
Jim can rent a car for maximum 4 days, therefore, he is not correct in his calculations.
