Shay and Nadine solve this problem in two different ways. Mark has $25 in his bank account. He makes $7 per hour babysitting. How many hours must he babysit to have a total of $165 in his account?.
Shay’s and Nadine’s methods use operations to simplify the expressions in order.
Shay’s method uses __________, but Nadine’s method does not.
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.
