Question

Nicole and Rhonda both babysit to earn extra money. The both charge a service fee plus an hourly rate. The amount Rhonda earns can be represented using the table below. The amount of money Nicole earns from babysitting can be represented by the equation y=7x+10. Who charges more per hour to babysit?. Justify your answer.

Answer 1

Nicole charges more per hour to babysit

Explanation:

We can assume form this problem, that the dependent variable is the money, dependent on the independent variable hours. This would mean x ⇒ hours, y ⇒ money.

Now if we take a look at Rhonda's pay rate, the rate would be;

1/3 ⇒ 0.333... ⇒ 1/3

The y-intercept represented by 2; Thus the equation being;

( Around ) y = 1/3x + 2

Now the two equations we have at hand are: y = 1/3x + 2, and y = 7x + 10. The first is Rhonda's charge, and Nicole's consecutively. Nicole's pay rate is generally more, provided a greater slope. We can see that y ⇒ money, and with a slope of 10 ⇒ Nicole works an hour for 10 ( dollars? ) each, while Rhonda works 3 hours for only 1 ( dollars? ) each, or 1 hour for 1/3 ( dollar? ) each.

* This concludes that Nicole charges more per hour to babysit *
