Question

alex sold wrapping paper rolls (r) as part of a school fundraiser. he earned a total of 156 reward points from his sales. using the equation 3r = 156, how many rolls of wrapping paper did alex sell?
a. 65
b. 26
c. 153
d. 52

Explanation:

Step1: Solve for \( r \)

To find the number of rolls \( r \), we need to isolate \( r \) in the equation \( 3r = 156 \). We do this by dividing both sides of the equation by 3.

$$ r=\frac{156}{3} $$

Step2: Calculate the value

Now we calculate \( \frac{156}{3} \).

$$ \frac{156}{3} = 52 $$

Answer:

D. 52
