Call x Andrew's age.

Then, Carol is 3 times older => Carol's age is 3x

And, Brad is 2 year older than Andrew => Brad's ages x + 2

In six years, Carol's age will be 3x + 6, Brad's age will be x + 2 + 6 and Andrew's age will be x + 6

Then, the sum of Andrew's and Brad's ages in six years will be:

(x + 6)+ (x + 2 + 6) = 3x + 6

Now, you can solve the equation:

x + 6 + x + 8 = 3x + 6

=> 3x - x - x = 8

=> x = 8.

So, today Carol's age = 3x = 3(8) = 24.

Answer: 24 years

One number is times a first number. A third number is 100 more than the first number. If the sum of the three numbers
icang [17]

When a number is 3 times a first number. A third number is 100 more than the first number and the sum of the three numbers is 450, the numbers are 70, 170 and 210.

<h3>How to calculate the numbers?</h3>

Let the first number = x

Second number = 3x

Third number = x + 100

Sum = 450

The numbers will be:

x + 3x + x + 100 = 450

5x + 100 = 450

5x = 450 - 100

5x = 350

Divide

x = 350 / 5

x = 70

First number = 70

Second number = 3x = 3 × 70 = 210

Third number = x + 100 = 70 + 100 = 170

Therefore, the numbers are 70, 170 and 210.

Setler [38]
First, the mark down 15% would make the value 85% of the original, so doing 15.99*0.85 gives you 13.59. Then take that and multiply that by 0.5, because of the half price, to get a final price of $6.79
