A teacher purchased some school supplies that cost $13 and $24. She had the remaining $6 budget from last year and for this year, she was given a $50 budget. How much money remains in her budget after purchasing the school supplies?
The teacher's total budget was $6 + $50 = $<T>add(6, 50)=56
Her total school supplies expenses was $13 + $24 = $<T>add(13, 24)=37
Hence, the teacher has $56 - $37 = $<T>subtract(56, 37)=19 remaining budget.
