In this video, I go through 4 examples of solving word problems involving systems of linear equations. The 4 examples are listed below with timestamps.
0:06 - Example 1: The cost of tickets for a movie is $3 for children and $5 for adults. If 300 movie tickets are sold and $1,260 is collected, how many tickets of each type were sold.
4:42 - Example 2: The cost of 5 tacos and 3 burritos is $19. The cost of 4
tacos and 8 burritos is $32. How much will 4 tacos and 5 burritos cost?
9:14 - Example 3: The sum of the ages of Tom and Mary is 32. 4 years ago, Tom was twice as old as Mary. How old are Tom and Mary now?
12:36 - Example 4: Tom has 67 coins that are worth a total of $4.75. All of Tom's coins are either nickels or quarters. How many of each coin does Tom have?
