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
