Question

camila is working two summer jobs,making $10 per hour lifeguarding and $6 per hour walking dogs. Camila worked 5 more hours lifeguarding than hours dog walking. She earned a total of $114

Answer 1

The number of hours she walked dogs for = 4 hours

The number of hours she worked as a life guard = 9 hours

Explanation:

Here, the earning per hour as lifeguard = $ 10

The earning per hour for walking dogs = $ 6

Let us assume the number of hours she worked for walking dog = m hours

So, The hours she worked as life guard = (m + 5) hours

Also, earning of Camilla for walking dog for m hours = m x ( 1 hour income)

= m x ($6) = 6 m

Earning of Camilla for working as a guard for (m +5) hours

= (m +5 )x ( 1 hour income) = (m +5) x ($ 10)

= 10 m + 50

Now, her TOTAL EARNING = $114

⇒ Earning from walking dogs + Life guard = $114

⇒ 6 m + 10 m + 50 = 114

or, 1 6 m = 64

or, m = 64/16 = 4

or, m = 4 hours

Hence, the number of hours she walked dogs for = 4 hours

The number of hours she worked as a life guard = 5 +4 = 9 hours
