Answer:
$63.06
Step-by-step explanation:
<em>Total Cost </em>
First, find the total cost for everything she bought
3 lamps at 23.59 each, and a sofa for 769.99
<u>Lamps </u>
Add 23.59 3 times, or multiply 3 times 23.59
23.59+23.59+23.59=70.77
23.59*3=70.77
<u>Total </u>
Add the lamps cost to the sofa cost
70.77+769.99=840.76
Sales Tax
Multiply the sales tax rate by her total cost
840.76 *7.5%
Convert 7.5% to a decimal by dividing by 100, or moving the decimal place 2 spots to the left
7.5/100=0.075
7.5--> .75-->0.075
840.76* 0.075=63.057
Round to the nearest cent, or hundreth: 63.06
The sales tax is: $63.06
