Salaria is growing oranges this summer. She bought two types of trees. She has 50% of tree A and 50% of tree B. Tree A gives her 10 oranges a month and 60% are good. Tree B gives her 15 oranges and 1/3 are good. If she gets 55 good oranges per month, how many total trees does she have?
Reason slowly and give your answer.
10
Each tree A gives her six good oranges a month 10 x.

6 = 6.

Each tree B gives her five good oranges a month because 15 x (1 / 3) = 5.

On average, a tree gives her 5.

5 oranges a month because.

5(6) +.

5(5) = 5.

5.

She has ten total trees because 55 / 5.

5 = 10.

.

So, the final answer is 10
