Answer:
x= 5
Step-by-step explanation: Theatres A and B make the same amount of money in one night. The equation for the two is 28x+20 for Theatre A, and Theatre B=22x+44. For the two theatres, 28 and 22 are the cost per ticket and 20 and 44 being the amount of food bought at the snack shop. X is the amount of people who attended either theatre. For them to have made the same amount of money in one night how many people attended? 5 people showed up to both theatres. 5 times 28 + 20 = 132. 5 times 22 +44 =132
