Agrocery store has a mark up of 30% on a bag of chips. if they purchase the chips for $1.50, what is the selling price of the chips?

Well first off you would go 1.50*0.30 which gives you 0.45

now take the original price of the chip bag and add the 0.45

which gives us 0.45+1.50 = 1.95 

hope this helps

Think of it as five or above give it a shove. change the 5 or above to the right to a zero and add one to the number on the left.
