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.)

Chelsea's guess of 85 plastic animals had a percent error of  2.29%.  

Aziz's guess must have been  722

gumballs or  798

gumballs 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

good job you smart son of a gun you are smarter that einstein. 7
