After 3.2 or 3 hours and 12 minutes, the total cost of services is equal.
Explanation:
First, set up equations for total cost for both Happy Paws and Woof Watchers.
x= number of hours
y= total cost
Happy Paws
y= 1.5x + 19
Woof Watchers
y= 2.75x + 15
Because you have to find when the total cost is equal, then the y's of both equations are equal to each other. That means you can substitute the Woof Watchers' 2.75x + 15 into the y of Happy Paws.
2.75x + 15 = 1.5x + 19
Rearrange the equation so the variable, x, is on one side and the numbers on the other and solve.
1.25x = 4
x= 3.2
You can check the answer by plugging 3.2 into x in the two equations and see if they yield the same total cost.
Happy Paws: 1.5(3.2) + 19 = 23.8
Woof Watchers: 2.75(3.2) + 15 = 23.8
Answer:
111.35
Step-by-step explanation:
effective rate: .085/12= .00708333333333
(fg)(x) = (3x + 6) (<span>2x^2)
</span>(fg)(x) = 6x^3 + 12x^2

Mr Pham's retirement account has 410 000 dollars. Let's put to a situation that he's not withdrawing from his account for several years, and this earns an annual interest of 3.85%.Let's find out how much will he earn: => 3.85% = 3.85% / 100% = .0385 => 410 000 * 0.0385 = 15 785 dollars.Mr, Pham will earn around 15 785 dollars in every year for 2 years he will earn times 2 of this amount that will be added to his retirement amount. => 15 785 dollars * 2 = 31570 dollars for 2 years and so on.<span>
