Reasoning The cost of making copies at Store W is $3 regardless of the number of copies. The cost of making copies at Store Z is 20¢ per copy plus a $1 charge for the use of the machine. The total
cost, c, of making n copies at either store can be represented by an equation. Write and graph a
system to find how many copies you have to make for the cost to be the same at both stores. Use
pencil and paper. If you have to make a small number of copies which store should you go to? If you
have to make a large number of copies which store should you go to? Explain.
Write the system of equations. Choose the correct answer below.

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!

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
