Question

After that incident, the Civil defense team decided to buy new trucks with ladders higher than 100 feet. They found 2 different trucks with same height of ladders. The first truck costs $145,000 and will cost $0.31 per mile traveled based on the current gas prices. The second truck will cost $160,000 but gets better gas mileage, costing $0.27 per mile. They need to decide which truck is the best deal.
1. Write an equation that represents the total cost of each truck.


2. How many miles the trucks will have to drive for the costs of the trucks to be equal?





3. Which truck should the Civil defense team buy? Explain your reasoning using Mathematical terms.

Answer 1

Answer:

Step-by-step explanation:

the cost difference between the first truck and the second truck = $160,000-$145,000 = $15,000

the difference of gas cost between the first truck and the second truck = $0.31 - $0.26= $0.05 per mile.

so,

I think, this is a very significant number of truck cost compared with gas cost

for the best deal, the first truck is the best choice.

Hope this answer helps you :)

Have a great day

Answer 2

Answer:

buy truck 2  since it cheaper

, if u do it in a graph after they intersect usee that truck num 1 increases while truck num 2 decreases

Step-by-step explanation:

1.

First Truck: Y = 0.31x + 145,000

Second Truck: Y = 0.27x + 160,000

2.

Y = 0.31x + 145,000

Y = 0.27x + 160,000

- 0.31x + y = 145,000

- 0.27x + y = 160,000

- 0.31x + y = 145000

0.27x – y = -160000

- 0.04 = -15000

X=375000

- 0.31 x 375000 + y =145000

Y = 261250

(x , y) = (375000 , 261250)
