Deborah bought a computer for 25% off the list price. If the list price is $2,428, how much did Deborah spend? A. $607 B. $1,821

Softa [21]

Answer:

Option A, $\$607$

Step-by-step explanation:

Given: Deborah bought a computer for $25\%$ off the list price.

The list price is $\$2,428$ .

To find: The amount Deborah spent on the computer.

Solution: We have,

List price of the computer $=\$2,428$ .

Deborah bought the computer for $25\%$ off the list price.

The amount Deborah spent on the computer $=25\% \times 2,428$

$=\frac{25}{100}\times2428=\frac{2428}{4} =\$ 607$ .

So, Deborah spent $\$607$ on the computer.

Hence, option A is correct.

Reverse the equation to find the radius (r)
The answer will be in pi form

32/81(pi)

8/20.25(pi)

Square root of 8/20.25(pi) = radius
