Math Problem of the Week - Upper Elementary - Aug. 29, 2021 to Sept. 4, 2021

Upper Elementary: 

Question: Henry teaches language lessons. His most expensive lessons cost 60 pounds, and his least expensive lessons cost 1 shilling. If 20 shillings make 1 pound, then what is the range in language lesson prices? Give your answer in pounds and shillings. 

Answer: 59 pounds and 19 shillings

Solution: We find the range by subtracting the smallest value from the largest value. So, the range in prices is 60 pounds - 1 shilling. Since there are 20 shillings to a pound, we borrow 20 shillings from 60 pounds to set up our subtraction equation: 59 pounds and 20 shillings - 1 shilling = 59 pounds and 19 shillings.
