Yanna bought ten shirts at $5 each and three pairs of sandals at $3 each.  How much change did she get back if she gave a one hundred dollar bill?
Ten shirts cost 10 x $5 = $<T>multiply(10, 5)=50
And, three pairs of sandals cost 3 x $3 = $<T>multiply(3, 3)=9
Thus, she spent $50 + $9= $<T>add(50, 9)=59
Therefore, she got back change of $100 - $59 = $<T>subtract(100, 59)=41
