each dog she walks, plus an additional $10.30 per hour that she walks the
dog. Each day she spends $4.50 on dog treats. Solve for how much money
Alexa would earn in one day if she worked for 5.5 hours.

well 10.30 x 5 = $51.50 and then half an hour would be $5.15 so that’s $56.65 for the hours. then plus the 3.75 that’s $60.40. and then minus the 4.50 that’s $55.90

Answer:

$55.90

Explanation:

First, create an equation representing her earnings each day.

Let x represent the number of hours that she walks the dog.

Since she charges $10.30 per hour, the cost from walking is 10.3x

She also charges $3.75 as a base fee, which has to be added

Putting this together, we get the equation y = 10.3x + 3.75

Plug in 5.5 as x to find her earnings:

y = 10.3x + 3.75

y = 10.3(5.5) + 3.75

y = 60.4

Since the spends $4.50 on dog treats a day, we have to subtract this from her earnings:

60.4 - 4.5

= 55.9

So, if she works for 5.5 hours, she will earn $55.90
