Q. At the school's holiday craft fair, Bernie and his classmates get to make gingerbread houses. Their teacher divides a bag of licorice ropes evenly among the

7

students at the table. Each student gets

5

licorice ropes to decorate the roof of his or her gingerbread house.

\newline

Which equation can you use to find the number of licorice ropes

r

that came in the bag?

\newline

Choices:

\newline

(A)

7r = 5

\newline

(B)

r + 7 = 5

\newline

(C)

r/7 = 5

\newline

(D)

r - 7 = 5

\newline

Solve this equation for

r

to find the number of licorice ropes that came in the bag.

\newline

\_\_\_

licorice ropes

Identify Correct Equation: First, let's figure out the correct equation to use. Each of the $7$ students gets $5$ ropes, so the total number of ropes, $r$ , is $7$ times the amount each student gets. The correct equation is $r = 7 \times 5$ .
Solve the Equation: Now, solve the equation $r = 7 \times 5$ . Calculate $7$ multiplied by $5$ .
