When it says varies directly, it means that y and x are going to be on opposite sides of the equals sign and that there is a constant, k,
y=kx
Plug in (5,100)
100=k(5)
K=20
The answer is .33333333
Because 8 divided by 24= .33333333
I hope this helps:)

Step-by-step explanation:
The wrong answers are deleted only the correct answers are listed below:
- Ryan earns $45 for 5 hours of work. The unit rate is $9 for 1 hour.
- Jenna can drive her car 110 miles on 5 gallons of gasoline. The unit rate is 22 miles per gallon.
- Claire saves $320 in 16 weeks. The unit rate is $20 per week.
- % increase in price of gas = [(New Price - Original Price) / Original Price] x 100
% increase in price of gas = [($2.48 - $2.18) / $2.18] x 100
% increase in price of gas = [$0.3 / $2.18] x 100
% increase in price of gas = 13.76%
Both is the answer to the problem
