Question

The price of the box of 10 markers is $7. The price of the box of 24 markers is $14. All prices without tax, and the price of the boxes is the same. Write an equation which tell the price Y for the number of markers X. QUICK!

Answer 1

Answer:

The price, Y, of X markers in dollars is

Y = 0.5X + 2

Step-by-step explanation:

Let the price of a box be B (According to the question, the price of the box is the same irrespective of the number of markers)

Let the price of a marker = A

The price of the box of 10 markers is $7. This is the price of the 10 markers and the box of markers.

7 = 10A + B

The price of the box of 24 markers is $14. This is the price of the 24 markers and the box of markers.

14 = 24A + B

Bringing the two equations together

7 = 10A + B

14 = 24A + B

Subtract the first equation from the second one

14 - 7 = 24A - 10A + B - B

7 = 14A

A = (7/14) = $0.5

7 = 10×0.5 + B

B = 7 - 5 = $2

Hence, the price of a marker = $0.5

Price of a box = $2

The price, Y, of X markers is thus given as

Y = 0.5X + 2

Hope this Helps!!!
