Answer:

Kelsey can buy 9 books.

Step-by-step explanation:

If Kelsey wants to buy as much books as possible with 30$, multiply 3$ by 9 (books) which is 27$.

30$-27$ is 3$ so she will have 3$ extra dollars to use for shipping. 2$ is the price for shipping so she will have an extra dollar.

The area of a parallelogram is given by

$A=bh$

Now, if we consider the 9.9 inches side as the base, then the height is the one labeled with 5.5 inches.

If instead we choose the 11 inches side as the base, the height is h.

So, we can express the area in this two equivalent ways:

$A = 9.9\cdot 5.5 = 11\cdot h$

Solving for h, we have

$h = \dfrac{9.9\cdot 5.5}{11} = 4.95$
