Question

Coach Johnson observed the track team practicing and predicted how many team members would be interested in jumping hurdles. When he then asked the team who was interested in jumping hurdles, 10 members raised their hands. Coach Johnson had predicted that 40% more members than that would raise a hand. How many team members had Coach Johnson predicted would be interested in jumping hurdles?

Answer 1

14

Step-by-step explanation:

10 team members and coach have predicted 40% so that is just too much. The coach has predicted the wrong

Since the amount of the Error percentage is 40% you have to turn 40 into 0.4

so 0.4 x 10 = 4

So the amount of the coach prediction was too big so add 4 with the actual number

10 + 4 = 14

So coach has anticipated that 14 team members would be interested in

jumping

so your answer would be 14

Answer 2

Coach Johnson predicted that 14 team members would be interested in jumping hurdles.

Step-by-step explanation:

To find out how many team members Coach Johnson predicted would be interested in jumping hurdles, we need to determine 40% more than the number of members who raised their hands.

Given that 10 members raised their hands, we can calculate 40% of 10 by multiplying 10 by 0.40, which gives us 4.

Adding 4 to the initial number of members who raised their hands gives us the predicted number: 10 + 4 = 14.
