Let P= $75, r=0.0054166, n= 40. In the future worth formula, F= P((1+r)^(n-1) -1) / r, it would yield a future worth of 3,247.16 at the age of 65. And the interest rate is I= (r^n-10)/(r-1). It yields an interest of 1.033

<h3>1.) Subtract 14 from both sides:</h3>
Cancels Out
<em> - We do this because we have to get 2 variables/numbers on each side of the equals, and the only way to do so is to cancels other numbers out by doing the opposite of what we see. </em>
<u>Equation at the end of Step 1: </u>
÷ 
<h3>2.) Multiply both sides by −0.8:</h3>

499 - 100%
599 - x
x = 599*100/499 = 120.04
x-100% = 120.04-100 = 20.04
Answer: The price increased by 20%.
Answer:
x = 12
Step-by-step explanation:
(whole secant) x (external part) = (whole secant) x (external part)
(6+x) *6 = (4+23) * 4
(6+x) *6 = 27*4
6(6+x) = 108
Divide each side by 6
6+x =18
Subtract 6 from each side
6+x-6 =18-6
x = 12
