Question

Lisa needs 125 pieces of candy for her guests at a party she is hosting. The candies come in packages of 35. She already has 20 pieces of candy left over from a previous party. How many packages of candy will Lisa have to buy to have 125 pieces of candy exactly? Create a two-step equation that models this problem and select which of the values below satisfies that equation.

Answer 1

Here you go ! 

Lisa needs = 125  candies

She already have = 20 candies

Each packet have = 35 candies  

125 - 20 = 105

So she needs 105 more candies.

105 ÷ 35 = 3 exactly 

She need to buy 3 packets of candies.



And for your equation :


Let the no. of packets be $x$ 


x = 125 - 20
x = 105 ÷ 35 
x = 3
