meal for each guest. which equation represents the relationship between the number of guests and the total cost?
number of guests-10. total cost ($)-300. number of guests-25. total cost-570

a. y - 10 = 18(x - 300)
b. y-300 = 18(x - 10)
c. y + 300 = 18(x + 10)
d. y-300 = -18(x - 10)
part b

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!
