Question

HELPPPPPPPPP

you are going to the fair. Your mom has generously given you $80 to spend at the fair and on an Uber home after the fair. It costs $10 to get into the fair and $3 per ride. You will need at least $10 left when you leave the fair to cover the cost of the Uber. Write a compound inequality modeling the situation. What is the maximum number if rides you will be able to afford to go on?

Answer 1

the maximum amount of rides is 20.

REASONING: you take away $20 from $80 so you can ride home on the Uber, and get in. then divide the remaining 60 by 3, leaving you with 20.

Answer 2

Explanation:

F=Fair cost, r=ride, U=uber cost. I=initial money

F=10+3r

The money you currently have($80) minus the $10 uber fee should be greater than 0 after the rides you went to. Here's the equation:

I-U>=10+3r

80-10>=10+3r

70>=10+3r=>Complex inequality

60>=3r

r<=20=>20 rides
