19. Tom and Sonia both mowed lawns last week. Tom mowed five lawns and charged \( \$ 10.75 \) per lawn. Sonia mowed four lawns but charged \( \$ 2.25 \) more per lawn than Tom. Who made the most money?

Tom earned \( 5 \times 10.75 = \$ 53.75 \) for mowing his five lawns. Sonia charged \( 10.75 + 2.25 = \$ 13.00 \) per lawn, and by mowing four lawns, she made \( 4 \times 13.00 = \$ 52.00 \). Therefore, Tom made the most money, earning \( \$ 53.75 \) compared to Sonia's \( \$ 52.00 \). Tom is like the dependable tortoise in a race, quietly and consistently earning a nice sum, while Sonia, the ambitious hare, charged a bit more but couldn't catch up in the end. Sometimes steady wins the race!
