You have a dog-walking business. You charge $12 per hour. Let's define n as the amount you earn and h as the number of
Goshia [24]

Answer:

n = 12h

Step-by-step explanation:

Given

r = 12/hr --- rate

h \to hours

n \to amount

Required

Determine which solution is correct or incorrect

The solutions are not given. So, I will provide a general explanation

The amount (n) is calculated as:

n = r  * h

So, we have:

n = 12  * h

n = 12h

The above is the general equation to solve for the amount, given h hours

When h = 2.5, we have:

n = 12*2.5

n = 30
