  1. Shay’s method uses equations, but Nadine’s method does not.

    Explanation: Shay likely set up an equation to represent the situation, such as ( 25 + 7h = 165 ), where ( h ) is the number of hours Mark must babysit. Nadine, on the other hand, may have approached the problem with a different method, possibly using estimation or a more straightforward calculation without formal equation setup, such as directly determining the difference between $165 and $25, then calculating how many $7 units fit into that difference.
