Question

Mia won 77 pieces of gum playing hoops at her schools game night. Later, she gave 3 each of her friends. She only has five reminding. How many friends does she have?

Answer 1

She has 24 friends.

Explanation

Suppose, the number of friends is  $x$

She gave 3 pieces of gum each of her friends. So, the total number of gums given to $x$ numbers of friends will be: $3x$

She had total 77 pieces of gums and after giving to her friends, she has only 5 remaining. So, the equation will be......

$3x+5=77\\ \\ 3x=77-5= 72\\ \\ x= \frac{72}{3}= 24$

So, she has total 24 friends.
