Answer:
61 sales
Step-by-step explanation:
First find the increase
45 * 35%
45*.35
15.75
Add this to your sales
45+15.75
60.75
Since you cannot have part of a sale, round up
61 sales

Answer:
9
Step-by-step explanation:
Since we know the number of contestants in Round 2, we could go step by step and calculate the number of remaining contestants in Round 3, then Round 4 and finally Round 5.
However, we can do it without calculating. So in Round 3, there will be:
R3 = R2^((n-1)/n), where n is number of the round
R3 = R2^(2/3)
For Round 4, the number will be:
R4 = (R2^(2/3))^(3/4)
And Round 5 will be:
R5 = ((R2^(2/3))^(3/4))^(4/5)
Threes and fives in exponents will cancel out and we'll remain only with:
R5 = R2^(2/5)
R5 = 249^(2/5)
R5 = 9.08
Rounded to the nearest integer, the number of contestants in Round 5 is 9.
