Question

Hey pineapple cost $5.04 together one banana and one pineapple cost the same as 13 banana what does one banana cost

Answer 1

Let P = pineapple cost

Let B = banana cost

 

Pineapple cost $5.04  ==>  P = 5.04

 

1 banana and 1 pineapple cost same as 13 bananas  ==>  B + P = 13*B

 

Plug in the value for P and solve for B 

 

B + 5.04 = 13*B

5.04 = 12*B

B = 0.42 

 

So one banana costs $0.42 

 

Check:  B + P = 5.04 + 0.42 = $5.46

            13*B  =  13*0.42 = $5.46
