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?
Salaria is growing oranges this summer. She bought two types of trees. She has [PERCENTAGE]% of tree A and [PERCENTAGE]% of tree B. Tree A gives her [NUMBER] oranges a month and [PERCENTAGE]% are good. Tree B gives her [NUMBER] oranges and [NUMBER] are good. If she gets [NUMBER] good oranges per month, how many total trees does she have?
Each tree A gives her six good oranges a month 10 x .6 = <<10*.6=6>>6
Each tree B gives her five good oranges a month because 15 x (1/3) = <<15*(1/3)=5>>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 = <<55/5.5=10>>10
