If something was regularly priced at $60 and was on sale for 30% off. the sales tax was 9%. what is the total coast including the sales tax?

$45.78

Step-by-step explanation:

Let's write out the required expression:

(1.00-0.30)($60)(1.09) = $45.78 (total cost, including tax)

Note that "30% off" translates into multiplying the original cost by 1.00 - 0.30, or 0.70.  Thus, the reduced price is 0.70($60) = $42.

Multiplying this result by 1.09 produces an output which includes both pre-tax cost of the item and the tax itself.

over the argument its not good to fight.

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
