Question

I will not promise but i will give 10pts and brainly to who ever answer correctly!!!!!!!!

Answer 1

Answer:  Malia's unit rate is greater than Bill's by $0.5.

Step-by-step explanation:

Since we have given that

Total amount earned by Malia is given by

y = 8.1 x

where, y is the total amount she earns in dollars and x is the number of hours she works.

In case of Bill works:

Number of hours   Total amount earned

18                                   $144.90

28                                  $225.40

35                                  $281.75

So, Unit price would be

$\dfrac{144.90}{18}=\dfrac{y}{x}\\\\8.05=\dfrac{y}{x}\\\\y=8.05x$

So, unit price of Malia is $8.1 whereas unit price of Bill is $8.05

So, Malia's unit rate is greater than Bill's by 8.10-8.05=$0.5.

Answer 2

The first thing you must do for this case is to find by using the provided table, the equation of the line that represents the amount of money earned per bill.
 For this case, the equation of the line is:
 y = 8.05x
 where is the number of hours worked and is the total amount he earns in dollars.
 Malia's equation on the other hand is
 y = 8.1x
 The rate of Malia is greater than bill's rate because she earns more money per hour than Bill.
 Malia earns 0.05 $ more per hour than Bill
 answer
 The rate of Malia is greater than bill's rate
