Roger and trevor went shopping for produce on the same day. they each bought some apples and some potatoes. the amount they bought and the total price they paid listed in the table below roger, apple(ib) 8, potatoes(ib) 7, total cost ($) 18.85 trevor, apples(ib) 2, potatoes(ib) 10, total cost($) 12.88 what was the price of apples and potatoes per pound?

Let x be price of apples per pound and y be price of potatoes per pound.

We can set a system of equations by our given information as:

Now we will use substitution method to solve our system of equations.

From equation 2 we will get,

Upon substituting value of x in equation 1 we will get,

Therefore, price of potatoes will be $0.99 per pound.

Now let us find price of apples by substituting y=0.99 in equation 2.

Therefore, price of apples will be $1.49 per pound.

step-by-step explanation:

consider the parallelogram shown in the attached image.

in the parallelogram hijk, the length of hk is given as,

from the properties of parallelogram we know that the opposite sides of a parallelogram are parallel to each other and are equal in measure.

therefore, the length of the side ij must be equal to the length of the side hk and that is .

hence, the expression for the length of ij confirms that hijk is a parallelogram.
