Answer:

$190.80.

Explanation:

So first let's figure out how much the computer cost after the sale. 10% = 0.10.

$1200 x 0.10 = $120. He got a $120 discount.

$1200 - $120 = $1080. This is the amount BEFORE tax.

Let's add on sales tax. 6% = 0.06.

$1080 x 0.06 = $64.80.

Now add the tax to the sale price.

$1080 + $64.80 = $1144.80 total discounted price with tax.

He is making 6 monthly payments, so divide this total by 6.

$1144.80 / 6 = $190.80.

(A quicker way. - - - 1200*(1-0.1)*1.06 = 1144.80 / 6 = 190.80).
