Question

Diane needs 165 pieces of candy to hand out to guests at a party she is hosting. Each bag of candy contains 20 pieces. She has 25 pieces left over from a previous party. She calculates she needs to purchase 7 additional bags of candy to meet the 165 piece of candy requirement. Which of the equations below verifies that she needs 7 additional bags of candy?

Answer 1

20x + 25 = 165

x represents the number of bags. You can solve the equation to make sure the answer is 7.

20x + 25 = 165

Subtract 25 from both sides.

20x = 140

Divide 20 off of both sides.

x = 7
