Lastweek she worked 5 hours at the kennel and earned a total of $185. How many hours did she work as acashier?

Answer 1

8.75 hours

Step-by-step explanation:

• She earns $10 per hour at the kennel

,

• She earns $12 per hour working as a cashier

,

• She also earns $30 a week babysitting.

Let the number of hours which she worked as a cashier = c

If she worked 5 hours at the kennel. her total income will be:

`10(5)+30+12c=185`

We then solve for c.

`\begin{gathered} 50+30+12c=185 \\ 12c=185-50-30 \\ 12c=185-80 \\ 12c=105 \\ c=(105)/(12) \\ c=8.75\text{ hours} \end{gathered}`

Linda worked for 8.75 hours as a cashier.
