D. No, Dynatashia paid too much for buns.

Step-by-step explanation:

We are given that,

The actual cost of the items are,

Items                                          Cost

Hamburger                         $3.99 per pound

Buns                                    $1.29 per packet

2-liter soda                          $2 per 3 bottle

As, she bought 1.5 pounds of hamburgers, 1 packet of buns and 3 bottles of 2-liter soda.

So, she has to pay,

For hamburger = 1.5 × 3.99 = $5.99

For buns = 1.29 × 1 = $1.29

For soda bottles = $2

But from the receipt, we see that she pays,

For hamburger = 1.5 × 3.99 = $5.99

For buns = 1.69 × 1 = $1.69

For soda bottles = 1.34 + 0.67 = $2

That is, she has to pay $1.29 for the packet of the buns but she paid $1.69 for the buns.

Hence, the receipt is not correct as Dynatashia paid too much for the buns.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
