Ms. Johnston's students counted by fives. The first person said, "Five." The next said, "Ten"; the next "15." They went all the

way up to 100. How many students counted to get to 100? Bobby said, "50." When asked how he knew, he said, "Because 5 is half of 10, and 50 is the same number as 5, just with a 0, and 10 is the same as 100 just with another 0."
How are you going to respond to Bobby? POST your response by WEDNESDAY. REPLY you other group members by SUNDAY - you agree with their approach to Bobby? How does it compare to your answer?

Answer:

20 students.

Step-by-step explanation:

The <u>first </u>person said 5 (which is 5 x 1), the <u>second </u>person said 10 ( which is 5 x2)... we see that this is a arithmetic sequence where the first term is 5 and the nth term is 100. We know that 100 = 5 x 20, therefore, the number of students that counted all the way up to 100 was 20 and Bobby was wrong.

mamaluj [8]
B= 2000 + CD
98000 = B + CD
substitute b in
98000 = 2000 + CD + CD
add variables
98000 = 2000 + 2CD
subtract 2000 from each side
96000 = 2CD
divide each side by 2
48000 = CD
