Question

There is a box of 14 DVDs worth $170.00. The box contains some DVDs

worth $10.00 each and some DVDs worth $15.00 each. Which system of
equations can be used to determine x, the number of $10.00 DVDs, and y, the
number of $15.00 DVDs?
Ο Α.
OB.
O C.
O D.
14x=170
y + x = 15
10x+15y = 14
x+y=170
x+14=170
10x+15y = 170
10x+15y = 170
x+y=14
12

Answer 1

To find the number of $10.00 DVDs (x) and the number of $15.00 DVDs (y), you can set up the following system of equations:

10x + 15y = 170

x + y = 14

Solving the system of equations yields x = 8 and y = 6.

Therefore, there are 8 DVDs worth $10.00 each and 6 DVDs worth $15.00 each in the box.
