Answer:
Rita must work 50 days to save at least $25.
Step-by-step explanation:
The amount Rita earns per hour = $10
The 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 = $25
So, 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 days
Hence, Rita must work 50 days to save at least $25.
