Answer:

$4.95

Step-by-step explanation:

Given: That an apple and an orange together cost $1.30

Further, 12 apples and 8 oranges together cost $13.40

Let the cost of an apple be $'x' and an orange be $'y'

∴ x+ y = 1.30...... (1)

&

12x + 8y = 13.40......(2)

Multiplying equation (1) by 12

12x + 12y = 15.6

Now, subtracting equation (2) from equation (1), we get

4y = 2.2

The cost of 9 oranges will be 9y

∴ 9y = 9/4*4y

⇒ 9/4*2.2

=$4.95
