Megan buys paint for her artwork. The graph shows the relationship between the
number of bottles of paint, x, she buys
and the ounces of paint, y, that she has.

What is an equation in terms of x and y
that can be used to model the
proportional relationship?

y=5x

each 1 ounce of paint is 5 bottles.

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!

the answer is 48m^2!
