Question 272225
let a = the price of one apple.
let b = the price of one banana.


2*a = 6*b


a + 2*b = 1.25


use the first equation to solve for a in terms of b.


you get a = 6*b/2 = 3*b


replace a with 3*b in the second equation to get:


3*b + 2*b = 1.25


combine like terms to get:


5*b = 1.25


divide both sides of the equation by 5 to get:


b = 1.25 / 5 = .25


price of 1 banana is $0.25


Since a = 3*b, this means that:


price of 1 apple is .75


substitute these values in your original equations to see that they are true.


your first equation is 2*a = 6*b


this means that 2*.75 = 6*.25


this means that 1.5 = 1.5 which is true.


your second equation is a + 2*b = 1.25


this means that .75 + 2*.25 = 1.25


this means that .75 + .50 = 1.25


this means that 1.25 = 1.25 which is also true.


price of one banana is $0.25 which is selection e.
