Answer: -5x^2y^4

Explanation: the only change you are able to make is the subtraction of 7 from 2 which gives -5 because you cannot subtract the x^2y^4 from x^2y^4 since it's multiplied by something else for each time it appears

Hope this helped! If it's wrong, I apologize :((

Raul is a saver. He sets aside $100 per month during his career of 40 years to prepare for retirement. He does not like the idea
Svet_ta [14]

The total balance in Raul's account after 40 years when he retires is $65,714.90.

<h3>What is the total balance?</h3>

The formula that can be used to determine the balance of the accout is: monthly amount saved x annuity factor.

Annuity factor = {[(1+r)^n] - 1} / r

Where:

  • r = interest rate = 1.5/12
  • n = number of periods = 12 x 40 = 480

$100 x [(1.00125^480) - 1 ] / 0.00125 = $65,714.90

Here is the complete question:

Raul is a saver. He sets aside $100 per month during his career of 40 years to prepare for retirement.

What is the balance in the account after 40 years?
