Question

Lauren walks dogs to earn extra money. She charges a flat fee of $10 per dog, plus $4 for every mile walked. How many miles would she need to walk a dog to earn $30 on one walk?

Answer 1

Lauren would need to walk 5 miles to earn $30 on one walk.

Step-by-step explanation:

To answer this question, we need to set up an equation.

The equation will represent the total amount of money Lauren earns for each dog walk. Let's say the number of miles she walks is represented by 'x'.

The flat fee she charges for each dog walk is $10, and she charges an additional $4 for every mile walked. So the equation is:

Total earnings = $10 + $4 * x

Now we can solve the equation to find the number of miles she would need to walk to earn $30:

$30 = $10 + $4 * x

$20 = $4 * x

x = $20 / $4

x = 5

Therefore, Lauren would need to walk 5 miles in order to earn $30 on one walk.
