Let's begin by calling Sarah's age now as X. As Ralph is 3 times as old as Sarah, X times 3 = 3X. Hence, Ralph's age is 3X. In six years, Ralph will be twice as old as Sarah. To calculate six years from now, add 6 to X for Sarah, and 6 to 3X for Ralph. As Ralph is twice as old as Sarah and we want to find the difference between the ages to calculate X, multiply X+6 by 2. You'll get 2X+12. Therefore, 2X+12=3X+6. Deduct 6 from 3X+6 as we want to isolate the variable. Because you did that to one side, you have to deduct 6 from 2X+12. Hence, now you have 2X+6=3X. X=6. Ralph's age is 3X, so 6 times 3 is 18. Ralph is 18 years old.

Answer:
The answer is D, $885.78
Step-by-step explanation:
If you use the calculator, then you can see that the money increases by 0.1% each year. For example, if you do 550*0.1 you get 55. add that to the 550 and you get 605, the second year's amount. If you keep doing this, when you get to year 6, you get 885.7805, or in money, $885.78! That's a lot of money!!! Hope this helps!
