8. Catherine and Bridget were participating in a physical fitness
contest. For every 3 sit-ups Catherine
did, Bridget did 5. If Bridget did 80 sit-
ups, how many did Catherine do?

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!

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
