How many donuts did Ms. Cowgill purchase in total if 6 donuts with sprinkles were eaten?

Question

Ms. Cowgill brought donuts for her advisory for meeting their semester 1 GPA goa of a 3.2 or higher. 30% of her advisory chose donuts with sprinkles because those are their favorite.

Answer 1

let x = the number of doughnuts that were purchased

 

then x multiplied by 30% = 6. After converting 30% to a decimal,

 

we have 0.3x = 6

 

divide both sides by 0.3 to get x = 6 ÷ 0.3

 

then x = 20
