The inequality 4x + 15 < 120 represents a real-world situation where x is a quantity that we are trying to find.
For example, let's say x represents the number of tickets you need to sell for a fundraiser event. The equation 4x + 15 < 120 would mean that if you sell x tickets, you will earn a profit less than $120.
To find the maximum number of tickets you can sell to meet this condition, we can solve the inequality:
4x + 15 < 120
Subtracting 15 from both sides:
4x < 120 - 15
Simplifying:
4x < 105
Dividing both sides by 4:
x < 26.25
This means that you can sell a maximum of 26 tickets (since you can't have a fraction of a ticket) and still earn a profit less than $120.
4x+15<120=26.25 as real world inequality
