Question

At Joe's Clown Car Rental Agency, renting a car costs $45 plus $0.75 for every mile it is driven. What is an equation that can be used to find the number of miles, m, a vehicle was driven, if the total rental charge was $222.50?

Answer 1

y=0.75m+45

Explanation:

when you bought the car it was 45, that doesnt change so its a constant

but every mile you drive, it changes, therefore it becomes the dependent or the rate :)

so we just make it into an equation of

y=0.75m+45

where y= the total amount of money owed

and if you wanted to solve for how far the car drove, plug in the 222.5 in for y, as that was the amount owed and solve!

222.5=0.75m+45

177.5=.75m

now divide by .75

m= 236 2/3 miles

hope this helped :))
