Dima wants to buy donuts for her classmates.
There are 18 students in her class.
She wants to buy 2x donuts for the classmates.
Then she will need to buy donuts that is double the number of her classmates.
Then, the number of donuts she will need = 2* number of classmates.
==> number of donuts = 2* number of classmates = 2*18 = 36
Then, Dima needs to buy 36 donuts for her classmates.
==> Then we she needs to buy 3 dozens of donuts.
To answer this question, multiply two times the number of students in the class, which is 18. Since 18 x 2 = 36, Dima wants to buy 36 donuts for her students to ensure that each gets two.
There are 18 students in Dima's class.
Dima wants 2 times as many donuts as the number of students in her class.
This means Dima wants to purchse purchse 2 times the number of students in her class.
So Dima wnats purchse 18*2 = 36 donuts as it 2times the number of students in her class.
The answer of 3 dozen doughnuts (36) is correct, according to the question. But I always think of the "outside the box" variables... what about the teacher and teacher aide?! While Dima will have to buy 3 dozen doughnuts for the class, I would buy 3-1/2 dozen which would include doughnuts for teacher, aide, and Dima herself! ;p
