Five students go through the lunch line. each student pays $1.85 for their lunch and gets 3 cookies. the total amount paid is $20.50.what is the cost of a cookie?

Hello there! The cost of a cookie is $0.72.

Start by multiplying the cost of lunch by 5 and subtract that from the total to get rid of the cost of lunch.

$1.85 x 5 = $9.25

$20 - $9.25 = $10.75

So, there were FIVE students and each bough THREE cookies. To find the cost for each cookie, first divide the total spent on cookies by 5 to get what each student spent on cookies, then by 3 to see how much each cookie cost.

$10.75/5 = $2.15

$2.15/3 = 0.716666667, which can be rounded to $0.72.

I hope this helps and have a great rest of your day!
