Step-by-step explanation:

Since 3 neckties will be out from the
store, so you need to know how much is the cost of 3 ties.
$59.99 x 3 = $179.97 and divide it by two
because the costumer will only pay for 2
$179.97 / 2 = $89.99 is the new price
Mark up = 89.99 – 59.99 = $30.00
% mark up = [(89.99/59.99) -1] * 100
= 50%

Whenever you issue a check, you deduct the amount from the balance of your checking account. When you deposit a check or cash, you add the amount to your balance.
In this way you can monitor the inflow and outflow of you cash so that you can stay within your budget.
