Q:
# The Changs updated their bedroom by purchasing a new lamp for $89.95 and a comforter set for $239.99. They paid 6 3/5 sales tax on their purchases. If the Changs paid $351.72 total, determine if they paid the correct amount.

Accepted Solution

A:

First, add the price of the lamp and comforter.

$239.99

+ 89.95

=329.94

Then put 6 3/5 into a decimal:

3/5= .6

6.6%

Then change it from a % by dividing by 100.

6.6%= .066

Then multiply 329.94 by 1.066

329.94 x 1.066 = 351.716

= 351.72

So, yes. they paid the correct amount
