-7w + 2(w + 8) = -24

First, expand your equation.
-7w + 2w + 16 = -24
Second, add '-7w + 2w' to get '5w'.
-5w + 16 = -24
Third, take away '16' from both sides.
-5w = -24 - 16
Fourth, subtract '-24 - 16' to get '-40'.
-5w = -40
Fifth, divide both sides by '-5' and change it into a positive.
w =  \frac{40}{5}
Sixth, how many times does 5 go into 40? 40 ÷ 5 = 8.
w = 8

Answer: w = 8

You want to purchase a new car in 5 years and you anticipate the cost of the car to be $55,000. You are given an investment plan
Usimov [2.4K]
Wow - that is an unusual calculation.  You'll need a formula for the monthly payment of a monthly annuity, and it is located here:
http://www.1728.org/annuity3.htm  (see formula 2)
You'll find THAT page and THIS page very helpful:
http://www.1728.org/annuitym.htm


rate = rate / 1,200
rate = <span> <span> <span> 0.005166666667 </span> </span> </span>
n= number of months = 5 * 12 = 60

monthly amount = [Total] / ([(1 + rate)^(n+1) -1] / [rate]) -1

monthly amount =
55,000 / [[( 1<span>.005166666667)^</span>(61)-1] /  1<span>.005166666667] -1
</span>
monthly amount = 55,000 / [[<span><span>1.3693761617</span> -1</span>] / .005166666667]-1
monthly amount = 55,000 / [[.3693761617] / .005166666667]-1
monthly amount = 55,000 / ((<span> <span> <span> 71.4921603244)-1)
</span></span></span>monthly amount = 55,000 / (<span> <span> 70.4921603244)</span></span>
<span><span><span>monthly amount = 780.2286062293 </span> </span> </span>
OR 780.23 (rounded)

Yes, it's just that "simple". LOL
