Jack has $43 in his piggy bank. He also gets an allowance of $10 a week. If Jack puts half of his allowance into his piggy bank every week, after 8 weeks how much will Jack have in his piggy bank?
Jack saves $10 / 2 = $<T>divide(10, 2)=5.0 a week.
Over 8 weeks Jack saves $5.00/week x 8 weeks = $<T>multiply(5.0, 8)=40.0
In total Jack has $43.00 + $40.00 = $<T>add(43, 40)=83 dollars in his piggy bank
