Question

If Scott started by asking 3 friends to sponsor him and each of those friends asked three friends how many sponsors would he have on the 4th week?

Answer 1

If Scott started by asking 3 friends to sponsor him, and each of those friends asked three friends, the number of sponsors would multiply by 3 each week.

In the first week, Scott would have 3 sponsors.
In the second week, each of the 3 sponsors would ask 3 friends, resulting in 3 * 3 = 9 sponsors.
In the third week, each of the 9 sponsors would ask 3 friends, resulting in 9 * 3 = 27 sponsors.

Therefore, on the fourth week, each of the 27 sponsors would ask 3 friends, resulting in 27 * 3 = 81 sponsors.

Scott would have 81 sponsors on the fourth week.

Answer 2

192 sponsors

Explanation:

If Scott started by asking 3 friends to sponsor him, and each of those friends asked three friends to sponsor him on the second week, and this pattern continued for four weeks, you can calculate the total number of sponsors he would have on the 4th week as follows:

Week 1: Scott has 3 sponsors.

Week 2: Each of the 3 sponsors from Week 1 asks 3 friends, so there are 3 x 3 = 9 new sponsors. In total, there are 3 (from Week 1) + 9 (from Week 2) = 12 sponsors.

Week 3: Each of the 12 sponsors from Week 2 asks 3 friends, so there are 12 x 3 = 36 new sponsors. In total, there are 12 (from Week 2) + 36 (from Week 3) = 48 sponsors.

Week 4: Each of the 48 sponsors from Week 3 asks 3 friends, so there are 48 x 3 = 144 new sponsors. In total, there are 48 (from Week 3) + 144 (from Week 4) = 192 sponsors.

So, on the 4th week, Scott would have a total of 192 sponsors.
