Wilma and Fernando went to the Farmer's Market on Saturday. Wilma bought 3 apples and 6 oranges for $9. Fernando bought 6 apples and 2 oranges for $7. What was the cost of 1 orange?

Enter numbers, decimals and - signs as needed, do not enter any other symbols or spaces)

The cost of 1 orange y = 1.1

Step-by-step explanation:

Let cost of 1 apple = x

Cost of 1 orange = y

We will make equations from given statements to find the cost of 1 orange i.e y

Wilma bought 3 apples and 6 oranges for $9: Mathematical expression will be:

Fernando bought 6 apples and 2 oranges for $7. Mathematical expression will be:

Let:

Multiply eq(1) by 2 and subtract both equations.

So, We get value of y=1.1

Now, put value of y in eq(1) to find value of x

So, the cost of 1 orange y = 1.1

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
