In order to find the cost after make up, we first try to find the price of the mark up. To do that, we multiply the cost by the percentage (remember to turn it into a decimal first).
$8.50 * .27 = $2.30
Now that we have this, we add the mark up to the original cost to get the new marked up cost.
Student A starts with $100 in the bank and makes $5 a day. Student B starts with $50 and makes $7 a day. Assuming the students save their money, when will they have the same amount of money ?
