Question

Dennis takes care of private swimming pools. He charges $50 to travel to a home and then $30 per hour. The equation t=50+30h models the total charge t for h hours of service. Find the ordered pair that presents 3 hours of work​

Answer 1

Answer:

(3, 140)

Step-by-step explanation:

If we have the equation $t = 50 + 30h$, we can substitute the value 3 as $h$ to find the value of $t$.

$t = 50 + 30(3)\\\\t = 50 + 90\\\\t = 140$

So we know that the total cost is $140.

To represent this as an ordered pair, we need to take note that the independent variable (x) is the one that we change to get the result (y).

We changed $h$ to get $t$, so $h$ is the x and $t$ is the y.

So it's represented as (3, 140).

Hope this helped!
