In a box there are many one-euro, two-euro, and five-euro coins. A dispencer draws coins out of the box - one at a time, and stops when three identical coins are taken out. What is the largest possible amount that can be withdrawn?
The answer is 21, please explain why

We want the biggest amount, so here goes:

1. one-euro

2. one-euro

3. two-euro     (he can't pick a one-euro here, otherwise he's done!)

4. two-euro

5. five-euro (he can't pick a two-euro here, otherwise he's done!)

6. five-euro

7. five-euro

1+1+2+2+5+5+5 = 21

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
