Two people each deliver food to people's homes. The amounts of money Peter and Maria each charge to deliver food are
described below.
• Peter charges a flat fee of $3.75 for each delivery plus $0.10 per mile for each
mile he drives.
• Maria charges a flat fee of $2.25 for each delivery plus $0.25 per mile for each
mile she drives.
Write an equation that represents Peter's charges to deliver food as
f(x)
and write
and equation that represents Maria's charge to deliver food as 9(x)..

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!
