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

Accepted Solution

A:

Answer:Rita must work 50 days to save at least $25.Step-by-step explanation:The amount Rita earns per hour = $10The saving percentage = 5%So, the savings of Rita per hour = 5% of $10⇒5% of $10 = [tex]\frac{5}{100} \times 10 = 0.5[/tex]or Rita saves $0.5 per hour.The amount she wants to save at minimum = $25So, let she works at the minimum of k Days.⇒[tex]\textrm{The number of hours she has to work} = \frac{\textrm{Amount she needs saving}}{\textrm{Amount saved in 1 hour}}[/tex]or, [tex]k = \frac{25}{0.5} = 50[/tex]The number of hours she has to work = 50 daysHence, Rita must work 50 days to save at least $25.
