Final answer:
To find out how many strawberries were in each box that Hannah bought, we can set up an equation using algebra. By solving the equation, we can determine that each box had 37 strawberries.
Step-by-step explanation:
To find out how many strawberries were in each box that Hannah bought, we can use algebra. Let's assume the number of strawberries in each box is 'x'. Since Hannah bought 3 boxes with the same number of strawberries, the total number of strawberries is 3x. According to the problem, Hannah and her friends ate 74 strawberries, leaving 37 strawberries. This can be represented by the equation 3x - 74 = 37.
To solve for x, we can start by adding 74 to both sides of the equation to isolate 3x. This gives us 3x = 111. Next, we divide both sides of the equation by 3 to solve for x. Therefore, x = 37.
So, each box of strawberries that Hannah bought had 37 strawberries.
