Apples sell for $1.90 per pound, and bananas sell for $0.75 per pound. Troy bought some apples and some bananas. Together they weighed 3.8 pounds, and cost $5.84.

Let p represent the number of pounds of apples Troy purchased.

Which equation represents the problem described here?

1.9p + 0.75 = 3.8

1.15p + 2.85 = 3.8

1.15p + 2.85 = 5.84

–1.15p + 2.85 = 5.84
