Jocelyn borrowed $500 from her mom for a new phone and wants to pay her back this month so that her debt to her mom is $0.

• $125 babysitting for family friends one Saturday and Sunday

• $50 doing chores around the house for a neighbor

• $75 mowing and doing additional yard work for another neighbor

Let x represent any additional money that Jocelyn needs to earn, if any, so that her total money earned equals $500.

Choose the equation that represents this situation. 

• -500-(125+50+75+x)=0

• -500+(125+50+75)=0

• -500+(125+50+75+x)=0

• 500+(125+50+75+x)=0
