B. 1.9 pounds of apples; 1.9 pounds of bananas

C. 2.6 pounds of apples; 1.2 pounds of bananas

D. 1.2 pounds of apples; 2.6 pound of bananas

Answer 1

a =pounds of apples, b = pounds of bananas
Now, write down 2 equations. Can you write one?

Answer 2

Hint:
Weight of a + Weight of b = 3.8
Cost of a + Cost of b = 5.84

Answer 3

Actually, since you're given the answers, you might notice that all of the answers sum to 3.8 when you add them together, so you can ignore the first equation. Just use your calculator to figure out which answer choice would give you a total cost of $5.84.
