Answer:

The number of hours she walked dogs for =  4 hours

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

Step-by-step 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
