Justin has 1200 dollars in his bank account and saves 30 a week Emmanuel has 3600 but spends 25 each week. when will they have the same amount of money?

1200 + 35w = 3600 - 25w

35w + 25w = 3600 - 1200

60w = 2400

w = 2400/60

w = 40 < = = 40 weeks

Justin : 1200 + 35 (40) = 1200 + 1400 = 2600

Emmanuel : 3600 - 25 (40) = 3600 - 1000 = 2600

so at 40 weeks, they both have $ 2600
