The equation for determining the original price of apple per pound is given as  

3 x (y + 0.75) = $5.88

Step-by-step explanation:

Let us represent the original price of apples per pound before winter with letter ‘y’

Since the price went up by $0.75, the new price per pound in winter will be = $(y + 0.75)  

Cost of 3 pounds of apple in winter = 3 * $(y + 0.75)

Amount Sam paid = Cost of 3 pounds of apple in winter = $5.88

Thus the equation for determining the original price of apple per pound is given as  

3 x (y + 0.75) = $5.88

To find the original price y, open the bracket and solve for y.

3 x y + 3 x 0.75 = 5.88

3y + 2.25 = 5.88

3y = 5.88 – 2.25

3y = 3.63

Divide through by 3

3y/3 = 3.63/3

y = $ 1.21

There, the original cost of apples per pound was $ 1.21

The new cost of apples per pound in winter = $ 1.21 + $ 0.75 = $ 1.96

Sam bought 3 pounds at the rate of $ 1.96 per pound  

Hence, he paid 3 x $ 1.96 = $ 5.88

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
