The answer to your question is 82.5
Ok, So Melissa bought 12 packages of stickers that cost $1.94 each before tax and 18 packages of paper that cost $3.29 each before tax. Which estimate is closest to the total cost before tax?
So 12 x 1.94 = 23.28$
then she bought 18 packages of paper that cost $3.29
So then 18 x 3.29 = 59.22$
Then add both of the totals 23.28 + 59.22$ = 82.5
There you have it the total cost is 82.5
So the total cost is 82.5
