Seth's father is thinking of buying his son a summer movie pass for $30 dollars. With the pass, matiness cost $4 each. Without the pass each movie is normally $8. If Seth plans to go to 30 movies this summer how much money would he
save?

Seth saved $90.

Step-by-step explanation:

1.Find out how much would be spent without buying the movie pass.

Multiply the amount of money that one would spend for each movie, by the number of movies one saw.

8 * 30 = 240

2.Find out the amount that was actually spent

Multiply the amount that was actually spent on each movie, by the number of movies that were seen. Then add the additional cost of the pass.

(4 * 30) + 30

= 120 + 30

= 150

3. Find the difference between the two values.

Subtract the amount that one was supposed to spend by the amount one did spend.

240 - 150

= 90

ab will be equal to

-9
