o There is a box of 14 DvDs worth $17o.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? O A. 10x+15y 170 x+ y 14 o B. 10x +15y 14 x+ y 170 O C. 14x 170 y x- 155 O D. x 14 170 10x+ 15y 170

Solution

There are \'x\' number of $10 DVDs . The cost of \'x\' DVDs would therefore be $10x

There are \'y\' number of $ 15 DVDs. The cost of \'y\' DVDs would therefor be $ 15y.

The total cost is $170. This means 10x +15y=170 and since total number of DVDs is 14, x+y= 14.

In view of the above the correct option to choose would be A
