Drew wants to buy exercise equipment that costs $140 and the sales tax is 5%. What is the total cost of the equipment? Since we are paying 100% of the price and 5% tax, that equals 105%. part = percent (in decimal form) x whole

Drew wants to buy exercise equipment that costs $140 and the sales tax is 5%. What is the total cost of the equipment? Since we are paying 100% of the price and 5% tax, that equals 105%. part = percent (in decimal form) x whole part = 1.05 · 140 = $147

What is the total cost of a $2.95 notebook if the tax is 5%? Since we are paying 100% of the price and 5% tax, that equals 105%. part = percent (in decimal form) x whole part = 1.05 · 2.95 = $3.10

A tip or gratuity is a small amount of money in return for a service. The total price is the regular price of the service plus the tip. A tip or gratuity is added onto the price of the item.

A haircut costs $20. Sales tax is 5% Is $25 sufficient to cover the haircut with tax and a 15% tip? 100% + 15% + 5% = 120$ part = percent (in decimal form) x whole part = 1.20 · 20 = $24.00 Yes, $25 is enough.

A store selling items for more than it pays for those items. The amount of increase is called the markup. The selling price is the amount the customer pays for an item. A markup is added onto the price of the item.
