We are given that car owners parallel park regularly = 26% .

And car owners don't park parallel regularly = 74%.

In order to check if Grafton picked the data fairly or not.

We need to check if the total sum of percentage of car owners parallel park regularly and percentage car owners don't park parallel regularly should be equal to 100.

If we add 26% + 74%, we get = 100%.

<h3>Therefore, Grafton picked the data fairly.</h3>

Usimov [2.4K]

Answer:

Ronnie spent 5 hours working.

Step-by-step explanation:

From the information given, the total cost of the job is equal to the flat fee plus the result of multiplying the cost per hour for the number of hours which is:

c=25+30x, where:

c is the total cost of the job

x is the number of hours

Now, you can replace c with 175 and solve for x:

175=25+30x

175-25=30x

150=30x

x=150/30

x=5

According to this, the answer is that Ronnie spent 5 hours working.
