Examine the following situation:
Each of 5 gift bags contains x pencils. Tyler adds 3 more pencils to each bag. Altogether, the gift bags contain 20 pencils.
Think about an equation that could represent this situation.
3
Multiple Choice
Choose the equation that represents the situation:
Each of 5 gift bags contains x pencils. Tyler adds 3 more pencils to each bag. Altogether, the gift bags contain 20 pencils.
5(x+3)=20
3(x+5)=20
x+3=20
20x=5
