Nissa and Alex know they picked 53 apples with 32 in one bucket. What expression helps find the number in the first bucket?

To determine how many apples are in the first bucket, you can set up an equation based on the total number of apples picked and the number of apples in one of the buckets. In this case, Nissa and Alex picked a total of 53 apples, and we know that 32 of those apples are in one bucket.

To find out how many apples are in the first bucket, you start by recognizing the relationship between the total number of apples and the apples in the known bucket. You want to express the total (53) as the sum of the apples in the first bucket (which we can represent with a variable) and the known amount in the second bucket (32).

This leads to the equation where the variable plus 32 equals 53. The correct expression can be interpreted as solving for the unknown quantity, represented here by the variable. Therefore, the equation can be set up as:

unknown amount + 32 = total number of apples (53).

This aligns with the correct choice, which sets up the equation needed to find the number of apples in the first bucket accurately.
