Answer:
8.8 hours
Step-by-step explanation:
Happy paws cost equation
5.50h + 20
Wood watchers cost equation
6.75h + 9
Make the two equations equal
5.50h+20 = 6.75h+ 9
Collect the co-efficient of both sides.
6.75h- 5.50h= 20-9
1.25h= 11
Divide both sides by the coefficient of h
1.25h/1.25= 11/1.25
h= 8.8
Answer:
8.8 hours
Equation :20+5.50h = 9 + 6.75 h
Step-by-step explanation:
Hi, to answer this question we have to write a Cost equation for each case:
For Happy Paws the cost will be equal to the fixed cost (20) plus the product of the cost per hour (5.50) and the number of hours (h).
Happy paws cost: 20+5.50 h
Same process for Woof Watchers:
Woof Watchers cost = 9 + 6.75 h
If both costs are equal:
Happy paws cost=Woof Watchers cost
So:
20+5.50h = 9 + 6.75 h
Solving for h
20-9 = 6.75h-5.50h
11 = 1.25h
11/ 1.25 =h
8.8 = h
