Question

You and two friends are planning a vacation. you want to keep the cost below $120 per person. Write and solve an inequity that represents the total cost of the vacation. Don't really need to be explained just the awnser please.

Answer 1

number of people: 3

x: cost per person

You want to keep the cost below $120 per person, then:

x < 120

Total cost = number of people * cost per person = 3x

Let's call y to the total cost, then y = 3x

x < 120 Multiplying by 3 at both sides

3x < 3*120

y < 360
