Bhavik bought 333 liters of milk and 555 loaves of bread for a total of \$11$11dollar sign, 11. A month later, he bought 444 lit
AnnZ [28]

Let the price of 1 litre of milk be  x$

Let the price of 1 loaf of bread be y$

According to the problem

333x + 555y =11

444x+444y=10

On subtracting the two,

We get

(333x+555y=11) * 444

(444x+444y= 10) * 333

(-)     (-)         (-)

147852x + 246420y =4884

147852x + 147852y = 3330

(-)            (-)                  (-)

------------------------------                   

 98568y = 1554     

           y = 1554/98568     

              = 0.0157$          

                 =0.02$    

Price of 1 loaf of bread= 2 cents    

On putting the value of y 

333x + 555*0.0157 = 11333x  + 8.7135 = 11333x = 2.2865x = 2.2865/333x = 0.00068$   = 0.01$

Price of 1 litre of milk = 1 cent

<u>Question 7</u>

  • The rate of change in Health Club A is 12 as given in slope-intercept form
  • The rate of change in Health Club B is 21 as given by an increase of $21 per month
  • The rate of change in Health Club C is 15 as given by (70-40)/(3-1)=15
  • The rate of change in Health Club D is 20 as given by "$20 each month for x months"
  • Therefore, Health Club B has the greatest rate of change of $21 per month

<u>Question 8:</u>

  • The initial value of Health Club A is 60 as given in slope-intercept form
  • The initial value of Health Club B is 0 as given by $0 for 0 months
  • The initial value of Health Club C is 25 as given by y=mx+b --> 40=15(1)+b --> b=25
  • The initial value of Health Club D is 20 as given by "A customer pays a one-time fee of $20"

Hello i don't get this answer at all if someone does please answer to this question
Naddika [18.5K]

Answer:

D

Step-by-step explanation:

To find the average, add up all of the values and then divide by the number of values.

So first, add (-5) + (-4) + (-7) + (-2) + (2) + (5)

You get -11. Then, divide -11 by the number of values (6)

-11/6 is about -1.83, which rounds to -2
