Mathematics: 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 hours you work. You want to make $30, so you figure you need to work 2.5 hours. Sort the solution methods by whether they are correct or incorrect methods to solve the problem.

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
