Question

You buy some living room furniture. The coffee table costs $189.99, the loveseat costs $249.95, the sofa costs $493.68, and 2 chairs cost $98.75 each. Sales tax is 7.25%. How much is your total purchase? $1,032.37 $1,213.13 $1,107.22 $1,131.12

Answer 1

For this case we have that the total of the purchase is given by:

Coffee table: $ 189.99

Loveseat: $ 249.95

Sofa: $ 493.68

2 chairs: 2 * $ 98.75 = $ 197.5

Adding up we have: $ 1131.12

Now, we must find the tax amount:

$ 1131.12 ----------> 100%

x ------------------------> 7.25%

Where "x" represents the value of the tax:

`x = \frac {7.25 * 1131.12} {100}\\x = 82.0062`

Finally, the amount to be paid is:

$ 1131.12 + $ 82.0062 = $ 1213.13

Answer:

Option B

Answer 2

Add the totals of each item together:

189.99 + 249.95 + 493.68 + 98.75 + 98.75 = 1,131.12

Now multiply that by the tax rate as a decimal:

1131.12 x 0.0725 = 82.01

Now add that to the total of the items:

1,131.12 + 82.01 = $1,213.13 total
