The number of DVDs sold at a store in a month was 921 and the number of DVDs sold decreased by 12
per month. The number of Blu-ray discs sold in the same store in the same month was 503 and the
number of Blu-ray discs sold increased by 26 per month. Let d represent the number of discs sold and t
represent the time in months.
d=921 - 12t
The system of equations
d = 503 +26t
can be used to represent this situation.
If this trend continues, how many months will the number of DVDs sold equal the number of Blu-ray discs
sold? How many of each is sold in that month?
