"A group of 8 friends goes to the movies. A bag of popcorn costs $2.99. How much will it cost to get one bag of popcorn for each friend? Explain how you can calculate this amount mentally. It will cost $ for all the friends to get popcorn. If the bags of popcorn for $3 each, it would cost $ . Since $2.99 is one cent less than $3, I
can subtract one cent for each friend, taking away $ from $24."

How do I solve this problem?

the olimpics is not going to wokk out

step-by-step explanation:

1st part is 64,000,000

2nd part 500,000

step-by-step explanation:

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5
