1) Plug the numbers into the equation for a simple interest rate. The equation is I = Prt, where P is the initial amount, r is the interest rate, and t is the time in years. 2) You have to turn the time into years, so put it over 12 (the months in a year) to turn it into a fraction for the unit of years, and plug in the equation to get I = 1200*0.81*(9/12). 3) Multiply this equation out to get 729.00, this is the answer. Answer: $729.00 interest. **TAKE THIS WITH A GRAIN OF SALT, you wrote the interest as dollars, but in this equation I assumed you meant to write it was a percent. If you did make a mistake and the 81 interest is a percent, then the math in this equation is correct. If it is an amount of money, then don’t copy it because it would be incorrect.
Hi there!
We can find the answer by factoring the equation, then setting them up equal to zero.
x² - 7x + 12 = 0
(x - 3)(x - 4) = 0
x - 3 = 0 x - 4 = 0
x = 3 x = 4
So you have two real solutions for the equation x² - 7x + 12 = 0.
Hope this helped! :)
