Group of 7 people spend 33.50 movie tickets 6.50 adults and 3.50 for child ticket. Which system of equation could be used to find the number adults tickets and child tickets purchased?

The answer is

x + y = 7

6.50x + 3.50y = 33.50

x - the number of adult tickets

y - the number of child tickets

Group of 7 people: x + y = 7

6.50 adults and 3.50 for child ticket cost 33.50: 6.50x + 3.50y = 33.50

So, we have two equations:

x + y = 7

6.50x + 3.50y = 33.50
