Aleesia lost 1.5 pounds each week for 10 weeks. Alexei lost 2.5 pounds each week for 8 weeks. How many pounds did the two friends combine to lose?
Alessia = 1.5 * 10 = <T>multiply(1.5, 10)=15.0 pounds
Alexei = 2.5 * 8 = <T>multiply(2.5, 8)=20.0 pounds
15 + 20 = <T>add(15, 20)=35 pounds
Together they lost 35 pounds.
