Question

Mitchell wants to order CDs on the Internet. Each CD costs $15.99, and shipping for the entire order is $9.99. Mitchell has no more than $100 to spend. What is the maximum number of CDs that Mitchell can order?

Answer 1

Answer:

maximum 5 CDs

Step-by-step explanation:

Let Mitchell can order a maximum of x CDs

It has been given that each CD costs $15.99, and shipping for the entire order is $9.99.

Thus, we have the total cost for x CDs

$15.99x+9.99$

Now, Mitchell has no more than $100 to spend. It means

$15.99x+9.99$

Subtract 9.99 to both sides

$15.99x$

Divide both sides by 15.99

$x$

Hence, Mitchell can order maximum 5 CDs

Answer 2

Hello!

The answer is: Mitchell can order a maximum of 5 CDs.

Why?

Let's make the entire shipping cost apart to calculate the actual money amount Mitchell could spend just buying CDs,

$Money To Spend = CDsPrice+ShippingPrice\\100=CDsPrice+9,99\\CDsPrice=100-9,99=90,1$

So, he will be able to spend 90,1 $

In order to calculate how many CDs Mitchell could buy with 90,1$, she/he should divide the total available amount by the CDs price which is 15,99$

Doing the calculation we have:

$\frac{90,1}{15,99} = 5,62$

So, since a CD is an indivisible object,  Mitchell can order a maximum of 5 CDs.

Have a nice day!
