Answer:

Therefore the cost of each apple is $ 0.50 and each banana is $1.

Step-by-step explanation:

Given , Amanda buys 6 apples and 5 bananas , it will cost $8.00 and if she buys 5 apples and 7 bananas it will cost $9.50.

Let the cost of one apple be =$ x

and the cost of one banana be =$y

According to the problem,

6x+5y=8.........(1)                  5x+7y= 9.50............(2)

Equation (1)×5 - equation (2) × 6

30x +25 y-(30x+42y)= 40-57

⇔30x+25y -30x-42y= -17

⇔-17y =-17

⇔y=1

putting the value of y in equation (1)

6x+5×1=8

⇔6x = 8-5

⇔6x=3

⇔x =\frac{3}{6}

⇔x = 0.50

Therefore the cost of each apple is $ 0.50 and each banana is $1.
