Solve the real-world situation by using the substitution method. The number of DVDs sold at a store in a month was 923 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 505 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 = 923 - 12t
The system of equations
can be used to represent this situation.
d = 505 + 26t
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?
There will be
DVDs and Blu-Ray discs sold per month in
months.
