Let us solve the problem using an equation. Let x be the number of months needed to make their saving equal. That is, after x months, their savings will be equal. The savings of Pedro after x months will be 180 + 20x (Amount already saved plus savings after x months @ 20/. per month) After x months, the savings of Jaclyn will be 120 + 40x (Amount already saved plus savings after x months @ 40/. per month) If their savings are equal after x months, the equation will be: 180 + 20x = 120 + 40x 180 - 120 = 40x - 20x 60 = 20x x = 60/20 = 3 So after 3 months, Jaclyn and Pedro will have saved the same amount of money
