Question

Joey's mother gave him $50 to pay his friend for helping to clean-up their garage. He gave each friend $8 and still had $2 left. The equation 8x + 2 = 50 can be used to find the number of friends (x) that helped clean-up the garage. How many friends helped clean-up the garage?

A) 4
B) 6
C) 8
D) 9

Answer 1

B) 6

Explanation:

If Total number of friends = x

Then from the equation we can can find the number of friends as;

8x + 2 = 50

Subtracting both sides by 2 we get;

8x = 48

Dividing both sides by 8 we get;

x = 6

Hence the total number of friends are 6.
