For Exercises 29-48, use a variation model to solve for the unknown value.
A rental car company charges a fixed amount to rent a car per day. Therefore, the cost per mile to rent a car for a given day is inversely proportional to the number of miles driven. if 100 mi is driven, the average daily cost is
a. Find the cost per mile if 200 mi is driven.
b. Find the cost per mile if 300 mi is driven.
c. Find the cost per mile if 400 mi is driven.
d. If the cost per mile is

- The force needed to break a board varies inversely with its length. If Tom uses 20 pounds of pressure to break a 1 .5-foot long board, how many pounds of pressure would he need to use to break a 6 foot long board?arrow_forwardAn airplane flies from Naples, Italy, in a straight line to Rome, Italy, which is 120 kilometers north and 150 kilometers west of Naples. How far does the plane fly?arrow_forwardThe distance a moving body travels, d, varies directly with time, t, it moves. A train travels 100 miles in 2 hours a. Write the equation that relates d and t. b. How many miles would it travel in 5 hours?arrow_forward
- The time required to empty a pool varies inversely as the rate of pumping. It took Lucy 2.5 hours to empty her pool using a pump that was rated at 400 gpm (gallons per minute). a. Write the equation of variation. b. How long will it take her to empty the pool using a pump rated at 500 gpm?arrow_forwardThe distance an object falls varies directly to the square of the time it falls. If an object falls 52.8 feet in 4 seconds, how far will it fall in 9 seconds?arrow_forwardIf you travel 100 miles in two hours, then your average speed for the trip is Average speed=_________=________arrow_forward

Her pay is $174 for 24 hours of work. Find how much she will get paid for 40 hours of work.arrow_forwardThe charge for a taxi ride in New York City is $3.00 for the first 1/4 of a mile, and then $0.40 for each additional 1/4 of a mile (rounded up to the nearest 1/4 mile). (a) Complete the table below for the cost C of going x miles in the taxi. Do not include a dollar sign in your answer. If the answer is $1.50, answer 1.50 or 1.5 (etc.). Miles, x 0 Cost, C 1/4 1/2 3/4 (b) How much would it cost to go 1/5 of a mile? $ (c) How much would it cost to go 6/5 of a mile? $ (d) How far could you go for $7.40? 1 5/4 3/2 7/4 (include help (units) in your answer) 2arrow_forward
- Depreciation is the decrease or loss in value of an item due to age, wear, or market conditions. We usually consider depreciation on expensive items like cars. Businesses use depreciation as a loss when calculating their income and taxes. One company buys a new bulldozer for $124850. The company depreciates the bulldozer linearly over its useful life of 20 years. Its salvage value at the end of 20 years is $12850. A) Express the value of the bulldozer, V, in terms of its age, t. V = B) The value of the bulldozer after 10 years is Şarrow_forward4B) The value of a car that cost $5000 new decreases by 15% every year. Write an equation for the value of the car. Use the equation and a graphing calculator to find the car's value for the first 3 years.arrow_forward
