Your work or words should justify your answer (explain how you know). As a math teacher, Josie frequently makes photocopies of fun activities for her students to do. When the copies come out of the copy machine, they form a stack. This table shows the relationship between the number of copies in the stack, x, and the height (in millimeters) of the stack, y. x (copies) y (millimeters) According to the values in the table, do x and y have a proportional relationship? yes no

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!
