Question

Rita earns $10 per hour. She puts 5% of her earnings in savings. Write an inequality to find how many hours h Rita must work to save at least $25

Answer 1

The inequality that will help you find how many hours Rita must work would be: 0.05x 10 x h is greater than or equal to 25

hope this helped you

Answer 2

For this case we have the following rule of three:

10 $ ----------> 100%

x --------------> 5%

Where "x" is the variable that represents 5% of $ 10.

`x = \frac {5 * 10} {100}\\x = 0.5`

Then Rita saves 0.5 $ per hour.

She wants to save at least $ 25. Then, we propose the following inequality:

`0.5h\geq 25`

ANswer:

`0.5h\geq 25`
