GrogVix [38]

Answer:

Part (A): The required expression is $55x$ .

Part (B): The correct option is C) the amount (in dollars) the company earns from each phone.

Step-by-step explanation:

Consider the provided information.

A used electronics store pays $50 for each cell phone, spends $15 refurbishing the phone, and sells the refurbished phone to a customer for $120.

Let x to represent the number of cell phones they sell.

Part (A)

For x cell phones store will pay $50x. Also store will spend $15x to refurbishing.

We will use negative sign for pay and spend money, Also use positive sign for selling amount.

Therefore the required expression is:

Company's earnings = $-50x-15x+120x$

Simplify the expression as shown.

$55x$

Hence, the required expression is $55x$ dollar

Part (B) What does the coefficient of the expression in part (a) represent?

The coefficient of the expression is the amount (in dollars) the company earns from each phone.

Hence, the correct option is C) the amount (in dollars) the company earns from each phone.

3 to the 2 power times 5 to the 3 times 8 divided by 3 times 5 to the 3 times 8

IceJOKER [234]

Answer:

Step-by-step explanation:

First condense all the numbers with exponents:

3² x 5³x 8 divided by 3 x 5³ x 8

27 x 125 x 8 divided by 3 x 27 x 8

Then multiply 27 , 125 ,and 8

27 x 125 x 8 =27000

Then multiply 3, 27 ,and 8

3 x 27 x 8 = 648

Then divide 27000 by 648

27000 / 648 = 41.6666666667

Which rounds to about: 42
