Just plug in 500 for p, 0.2 for r (because 20% is equivalent to 0.20), and 2 for t:

So, if you start with $500 and charge an interest rate of 20% for 2 years, you will gain $200 to get $700 in total.
You can find a common denominator using the two denominators multiples.
Answer:
Sample Response: First, the like terms had to be combined using the lowest common denominator (LCD). Then the subtraction property of equality was used to isolate the variable term. Finally, both sides of the equation were multiplied by the reciprocal of the coefficient to solve for a.
Step-by-step explanation:
Answer:
x=6
Step-by-step explanation:
distribute 2 to x and 3..you get 2x -6 +1. add 6 and subtract one to cancel it out and bring it to the other side. 2x=12...simplify x=6
