Step-by-step explanation:
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.

The current grading rate is
(30 minute)/(5 papers) = 6 minutes/paper.
She has 3 hours (or 180 minutes) to grade 35 papers.
She now has 180 - 30 = 150 minutes left, and she has 35- 5 = 30 papers left.
The remaining grading rate is
(150 minutes)/(30 papers) = 5 minutes/paper
Therefore she must work at 1 minute/paper faster to complete grading 35 papers in 3 hours.
Answer: She should work faster at an increased rate of 1 minute per paper.
It would be $4.60 because $2.30x2=4.60
