Sam's Fruit Cellar earns a $0.40 profit for each apple that it sells and a $0.40 profit for each banana that it sells. Which expression shows Sam's total profits from selling apples (a) and bananas (b)?

A.
0.40(ab)

B.
0.40(a + b)

C.
0.40 + a + 0.40 + b

D.
0.80(ab)

is it d?

The correct expression that shows Sam's total profits from selling apples (a) and bananas (b) is B. 0.40(a + b). Each apple earns a profit of $0.40 and each banana also earns a profit of $0.40. By multiplying $0.40 by the sum of the number of apples and bananas sold (a + b), we can calculate the total profits from selling both fruits.
