Question

Zach read a book for 10 minutes every weekend in the first month, 20 minutes in the second month, 40 minutes in the third month, and 80 minutes in the fourth month.
Victoria read a book for 35 minutes every weekend in the first month, 50 minutes in the second month, 65 minutes in the third month, and 80 minutes in the fourth month.

Which statement best describes the methods used by Zach and Victoria to increase the time they spent reading



A) Zach's method is linear because the number of minutes increased by an equal factor every month.
B) Victoria's method is linear because the number of minutes increased by an equal number every month.
C) Both Victoria's and Zach's methods are exponential because the number of minutes increased by an equal factor every month.
D) Both Victoria's and Zach's methods are exponential because the number of minutes increased by an equal number every month.

Answer 1

The answer is B.

This is because A is incorrect, Zach number of minutes didnt increase by an equal factor every month.

C and D are incorrect, Victoria's methods aren't exponential, but Zach's are.

So that leaves the only reasonable answer which is B.
