Answer:
The price, Y, of X markers in dollars is
Y = 0.5X + 2
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!!!
