Answer:

x = 73

General Formulas and Concepts:

  • Order of Operations: BPEMDAS

Step-by-step explanation:

<u>Step 1: Define equation</u>

(180 - x) + (90 - x) = 124

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Combine like terms:                         270 - 2x = 124
  2. Subtract 270 on both sides:            -2x = -146
  3. Divide -2 on both sides:                   x = 73

<u>Step 3: Check</u>

<em>Plug in x to verify it's a solution.</em>

  1. Substitute:                         (180 - 73) + (90 - 73) = 124
  2. Subtract:                            107 + 17 = 124
  3. Add:                                   124 = 124

You have $250,000 in an IRA individual Retirement Account at the time you retire. You have the option this money in two funds: F
love history [14]
So to start off with this problem, let us call the amount invested in Plan A and B as a and b respectively.

So equation 1: a + b = 250,000

Next, we need to get an equation which is equal to 10,000. So the interest rate in plan a + interest rate in plan b would be equal to 10,000. Rewriting this sentence will give us:

Equation 2: .028a + 0.078b = 10,000

Rewrite the first equation into a = 250,000 - b, and then plug the value into equation 2.

.028(250,000 - b) + 0.078b = 10,000

7,000 - 0.028b + 0.078b = 10,000
-0.028b + 0.078b = 10,000 - 7,000
0.05b = 3,000
b = $60000 amount invested at 2.8% while 
250,000 - 60,000 = $190,000 is the amount invested at 7.8%
