Tom's and Tim's ages add up to 21 years. In 3 years, Tom will be twice Tim’s age. How old are they now? A. Tom is 15, and Tim is

Ierofanga [76]

Answer:

A. Tom is 15, and Tim is 6.

Step-by-step explanation:

Method A: Use the choices to find the answer

Since you are given choices, you can try each choice until you see that one of the choices works.

Try choice A.

Ages now: 15 + 6 = 21 (This checks out.)

Ages in 3 years: Tom 15 + 3; Tim 6 + 3

(15 + 3)/(6 + 3) = 18/9 = 2 (This also checks out.)

The first choice works, so the answer is A.

Method B: Write an equation to solve the problem

Let Tom's age now = t.

Their ages add to 21, so Tim's age now is 21 - t.

In 3 years, Tom's age will be t + 3, and Tim's age will be 24 - t.

In 3 years, Tom's age will be twice Tim's age:

t + 3 = 2(24 - t)

t + 3 = 48 - 2t

3t = 45

t = 15

Tom's age is 15.

Tim's age is 21 - 15 = 6.

Tim's age is 6.

ANEK [815]

Complete question :

You have decided to stop drinking Starbucks coffee and invest that money in an IRA. If you deposit $492 each month earning 6% interest, how much will you have in the account after 40 years?

Answer:

$250,329.60

Step-by-step explanation:

Given:

Principal, P= $492 per month

= $492 * 12 = $5,904 per year

Rate, R= 6%

Time, T= 40 years

Let's first find the amount after 40 years.

Amount = 5940 * 40 = $236,160

The interest after 40 years =

$Interest = \frac{PRT}{100} = \frac{5904 * 6 * 40}{100}$

Interest = $14,169.60

The total amount I will have in my account after 40 years:

Amount + interest

= $236,160 + $14,169.60

= $250,329.60
