Sue buys a certain brand of cereal that costs $12 per box. sue changes to a super-saving brand of the same size. the equation shows the price, y, as a function of the number of boxes, x, for the new brand. y = 8x how much money does sue save each month with the change in cereal brand if she buys 4 cereal boxes each month?

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!

a is the right answer
