Pples are on sale for $5 for 10 apples. chicken is on sale: 5 pounds for $8.00. if i purchased 8 lbs of chicken and 7 apples at these prices, how much money would i get back if i paid with a $20 bill?

7*2= $14   ( apples )

8*1.6= $12.8  ( chicken )

$14+$12.80= $26.80  ( total )

you wouldn't have enough money if you had only a 20$ bill

unless you spent 20$ bill at each station making you have 40$ and you would have $13.20

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
