The local movie theater offers a discount card for movies. For $10, you can purchase a card, then each movie ticket will cost $5. Write a linear equation to model this situation, then determine the total cost of 3 tickets.

c = 10 +5*x

$25

Step-by-step explanation:

To obtain the linear equation we must first determine our variable, which would be the number of tickets to be purchased.

That is, the equation would be the initial investment added to the value of each ticket, like this:

c = 10 +5*x

Now, for the value of 3 tickets we replaced and have left:

c = 10 + 5*3

c = 25

which means it's worth $25 the 3 tickets

b - exponent
