Answer:
A) The number of hours for service charge of both to be equal is 7 hours 12 minutes
B) Total cost of services is $45.2
Step-by-step explanation:
Given as :
The fixed charge taken by Happy Paws = $20
The moving charge taken by Happy Paws = $3.50 per hours
The fixed charge taken by Woof Watchers = $11
The moving charge taken by Woof Watchers = $4.75 per hours
Let The number of hours for service charge of both to be equal = n hours
Let The total cost of services = $A
<u>According to question</u>
For service charge of both to be equal
The fixed charge taken by Happy Paws + moving charge taken by Happy Paws × number of hours for service charge = The fixed charge taken by Woof Watchers + moving charge taken by Woof Watchers × number of hours for service charge
i.e $20 + $3.50 × n = $11 + $4.75 × n
Or, $20 - $11 = $4.75 × n - $3.50 × n
Or, $9 = $1.25 × n
∴ n =
i.e n = 7.2 hours
So, The number of hours for service charge of both to be equal = n = 7 hours 12 minutes
Hence , The number of hours for service charge of both to be equal is 7 hours 12 minutes . Answer
<u>Again</u>
Total cost of services = $11 + $4.75 × n
i.e A = $11 + $4.75 × 7.2
Or, A = $11 + $34.2
Or. A = $45.2
So, Total cost of services = A= $45.2
Hence, Total cost of services is $45.2 Answer
