Final answer:
To calculate the total number of apples, T, that Naomi has, we use the formula T = 5b + 28c, where b is the number of bags of apples, and c is the number of crates, with 5 apples per bag and 28 apples per crate.
Step-by-step explanation:
The student is asking for a formula to represent the total number of apples, T, that Naomi has, in terms of the number of bags of apples, b, and the number of crates of apples, c. Since there are 5 apples in each bag and 28 apples in each crate, we can create the formula.
The total number of apples in the bags is simply the number of bags, b, multiplied by the 5 apples per bag. Therefore, this part of the equation is 5b.
Similarly, the total number of apples in the crates is the number of crates, c, multiplied by the 28 apples per crate, yielding 28c.
To find the total, T, we add the number of apples from the bags and crates together, which gives us the equation:
T = 5b + 28c
