Some people are guessing the number of jelly beans in a jar. Each person who guesses within 15 of the correct number will win a prize. The correct number of jelly beans is 389. What values of n represent the numbers that will win a prize
389 - 15 = 374
389 + 15 = 404
374 < n < 404
THose should be greater than or less than signs
To determine the values of n that will win a prize, we need to find the range within 15 of the correct number of jelly beans, which is 389.
To find the lower bound, we subtract 15 from the correct number:
Lower bound = 389 - 15 = 374
To find the upper bound, we add 15 to the correct number:
Upper bound = 389 + 15 = 404
Therefore, the values of n that represent the numbers that will win a prize are all the numbers between 374 and 404 (inclusive), or in interval notation, [374, 404].
