Hello!
You would first want to substitute the values given where x=4 and z=3 giving you
8(4)^2 + (51/3)
Next, you want to multiply 4 times itself giving you 8(16) + (51/3)
Then multiply 8(16) giving you 128 + (51/3)
Multiply 128 by 3 to match the denominators giving you
(384/3) + (51/3)
Add together giving (435/3) and divide to give you the answer of 145

The price of a candy bar is $1.53. If this is three cents more than triple the price ten years ago, how much did the candy bar c
Tamiku [17]

Answer:

$0.51

Step-by-step explanation:

Hello! Using what we know, the price of the candy bar at the moment is $1.53, triple the price from 10 years ago. So, triple cents would technically be $0.03. We divide $1.53 and $0.03 and get 51! But, it would not make sense for the price ten years ago to be 51 then go to 1.53, so we make 51 a decimal, 0.51. We can check to see if this correct, by doing 0.51 times 3, because the price is tripling, and we get $1.53! Have an awesome day! :)

A trader old a writ watch for h.3150 after giving a 10% dicount.Find the marked price of the watch
vivado [14]

The marked price of the wrist watch after the trader sold a wrist watch for $3150 after giving a 10% discount is $3500.

First, let us understand the percentage:

A percentage is a fraction of a whole expressed as a number between 0 and 100. Nothing is zero percent, everything is 100 percent, half of everything is fifty percent, and nothing is zero percent.

To determine a percentage, we need to divide the portion of the whole by the whole itself and multiply by 100.

Let the marked price be x.

So,

According to the question;

x - x * 10% = 3150

x - x * 10/100 = 3150

100x - 10x / 100 = 3150

90x = 3150 * 100

x = 3150 * 100 / 90

x = 3500

So, the marked price is $3500.

Thus, the marked price of the wrist watch after the trader sold a wrist watch for $3150 after giving a 10% discount is $3500.
