Lillie's bill at the store was $31.00. She spent $2.25 on each of 5 boxes of cake mix. She spent $2.80 on each of 4 gallons of milk. She also bought 5 cartons of eggs. How much did each carton of eggs cost?

each carton of eggs cost $1.71

Step-by-step explanation:

We know she spent a total of $31 at the store.

2.25 for 1 box of cake mix

times by 5

11.25 for 5 box of cake mix

2.80 for 1 gallons of milk

times by 4

11.20 for 4 gallons of milks

add that all up

11.25+11.20=22.45

Take away

31-22.45=8.55 that's for 5 cartons of eggs but we want them individually.

so divide by t

8.55÷5=1.71

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!
