A person needs to rent a 12-foot moving truck for a day. He calls two rental companies to determine their fee structure. The first company charges $25 plus $0.40 per mile, and the second company charges $35 plus $0.30 per mile. After how many miles will the cost of renting the truck be the same? What is the cost at this mileage?

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
