Question

The original price of a camera is $150. If a discount of 30% is given, what is the discounted price of the camera?

Answer 1

So, 30% is 0.30, but since you are taking off 30%, you are going to have 70% of the price which is 0.70. The word "of" lets you know that you are going to multiply. So, what you do is 150•0.70=105. The discounted price is $105

Answer 2

Answer:

The discounted price of the camera is $105

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

Before we can solve this question we need to create an expression to calculate the final discounted price of the camera. The expression would be,

$T = 150 * (1-r)$

Where:

• T is the total discounted price
• r is the percent rate in decimal form

Before we can use the formula we need to get the percent in decimal form by moving the decimal two digits to the left. Once we have that we can plug the values in the formula and solve for T.

30%   ⇔   0.30

$T = 150 * (1-r)$

$T = 150 * (1-0.30)$

$T = 150 * 0.70$

$T = 105$

So we see that the discounted price of the camera is $105
