Question

You have $60 and your sister has $120.You are saving $7 per week and your sister is saving $5 per week. How long will it be before you and your sister have the same amount of money? Write an equation and solve

Answer 1

# of weeks = n

total amount of money = t

t= 60 + 7n

t= 120 + 5n

120 + 5n = 60 + 7n

2n = 60

n = 30

You and your sister will have the same amount of money after 30 weeks
