The school library is having a competition for the book fair. Students must guess the number of plastic animals in a large jar, or the number of gumballs in another large jar. The students with the closest guess for each jar will win a free book.

Chelsea had the closest guess of 85 for the plastic animals, which actually had 87 plastic animals in the jar. Aziz had the closest guess with an error of 5% for the gumballs, which actually had 760 gumballs in the jar.

Use the given information to complete the following sentences.

Chelsea’s guess of 85 plastic animals had a percent error of

%.

Aziz’s guess must have been

gumballs or

gumballs since his guess had a percent error of 5%. (Note: place the smaller of the guesses in the first box.)

Answer:Chelsea’s guess of 85 plastic animals had a percent error of 2.29%.Aziz’s guess must have been 722

gumballs or 798gumballs since his guess had a percent error of 5%.Step-by-step explanation:Number of plastic animals in a jar = 87

Chelsea’s guess of number of animals = 85

Difference = 87 – 85

Hence, error percentage of Chelsea’s guess = 2/87 * 100

= 2.29%

Number of gumballs = 760

Error percentage = 5%

Difference between number of gumballs and Aziz’s guess = 760 * 0.05

= 38

Hence, Aziz’s guess for number of gumballs = 760-38 (or) 760+38

= 722 (or) 798

Answer:okey is 2.3% and Therefore, Aziz’s guess must have been 722 gumballs or 798 gumballs

Step-by-step explanation:Percent error can be used to compare a student’s guess to an actual amount. It is found by taking the difference between the student’s guess and the actual amount and then dividing by the actual amount. Use the following formula to find the percent error of Chelsea’s guess.

So, Chelsea’s guess of 85 plastic animals had a percent error of 2.3%.

To find the possible guesses Aziz could have made with a 5% error, multiply the percent error by the actual amount of gumballs in the jar.

So, Aziz’s guess was 38 gumballs away from the actual amount, which means he either guessed over or under by that amount.

Therefore, Aziz’s guess must have been 722 gumballs or 798 gumballs since his guess had a percent error of 5%.
