Question

Nilda has $250 in her savings account. She plans to save $15 per week from her salary. Iona has only $200 in her account but can save $20 a week from her paycheck. How many weeks will it take before the amount in each savings account is the same?

Answer 1

10 weeks

Explanation:

Nilda's money = 250 + 15x

Lona's money = 200 + 20x

250 + 15x = 200 + 20x

250 - 200 = (20 - 15)x

50 = 5x

10 = x

Answer 2

Answer: 10 weeks

Explanation:

Nilda's money = 250 +15x being x the number of weeks that have passed

Lona's money= 200+20x

If they have the same amount, then

250+15x=200+20x

250-200=(20-15)x

50=5x

50/5=x

10=x
