Can you show your work 12/2=9/?
timama [110]
Since this is a proportion, we cross multiply.
12/2=9/x (The variable "x" is used the represent the unknown number, and this is the number we are solving for)
12*x=2*9 (Cross multiply)
12x=18 (Simplify)
x=18/12 (Divide each side by 12)
x = 3/2 (Simplify fraction)
The unknown number is 3/2, or 1.5.

cupoosta [38]

Answer:

Selling price = $1242.85

Step-by-step explanation:

Given the following data;

Cost price = $1,675

Discount = 30%

Sales tax rate = 6%

To find the selling price;

First of all, we would determine the discount price.

Discount price = 30/100 * 1675

Discount price = 50250/100

Discount price = $502.5

New price = cost price - discount

New price = 1675 - 502.5

New price = $1172.5

Next, we calculate the sales tax.

Sales tax price = 6/100 * 1172.5

Sales tax price = 7035/100

Sales tax price = 70.35

Now, we can determine the selling price after discount and sales tax;

Selling price = 1172.5 + 70.35

Selling price = $1242.85

Therefore, you will pay $1242.85 for the laptop computer.
