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? (There will be a variable on both sides of the equation)

Answer 1

30 weeks

Explanation:

for this equation a will be the number of weeks

you have, 60 + 7a

she has, 120 + 5a

60+7a = 120 + 5a

2a = 60

a = 30 weeks
