Maria went to the grocery store and bought eight items .she bought two cartons of eggs at $2.15 each , a loaf of bread for $1.89, three steaks for $6.95 each , a bag of potatoes for $4.05, and 1 gallon of milk for $1.99 what is the approximate average cost per item for maria’s grocery store purchase

$ 4.135 is the average cost of per item

Step-by-step explanation:

Total items bought = 8

Total eggs cartons bought = 2

Price of one egg carton = $ 2.15

Price of two egg cartons = 2 * $ 2.15

                                         = $ 4.30

Price of loaf of bread = $ 1.89

Total steaks bought = 3

Price of one steak = $ 6.95

Price of 3 steaks = 3 * $ 6.95

                            =$ 20.85

Price of bag f potato = $ 4.05

Price of gallon of milk = $ 1.99

Total Price of all the items =  4.30+1.89+20.85+4.05+1.99

                                            = $ 33.08

Approximate average cost per item = Total price / No of items bought

Putting in the values

Average cost =

                      = $ 4.135

answer: 20

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
