Brian paid $7.84 at the grocery store for carrots and potatoes. He bought 5 pounds of carrots at $0.89 per pound and 3 pounds of potatoes. How much did Brian pay per pound for the potatoes he bought?

A. $1.03

B . $3.39

C . $2.32

D . $1.13

$1.13 (D)

Step-by-step explanation:

You would first have to find out the total cost of the carrots. To do this, we would take the number of pounds (5), and multiply it by the cost per pound ($0.89). 5×.89=4.45

Then, you would have to subtract 4.45 from Brian's total to find out how much he payed for the potatoes in total. $7.84-$4.45= $3.39. We now know how much Brian payed for the potatoes alone.

But since the question asks you to find how much it costs per pound, you would then divide the amount Brian payed for the potatoes by how many pounds of them he bought. In this case, Brian bought 3 pounds of potatoes.  $3.39÷3= $1.13

Brian payed a total of $1.13 per pound of potatoes.

  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.
