Answer:
$25
Step-by-step explanation:
Since it was originally $100, 80% off would mean he would only have to pay $20 for it. But sales tax, you would have to add 10% back of the sale price which was $20. so, 10% of 20 is $5. The sale price, $20, plus the $5 is 25 dollars he had to pay.
150
360 - (130 + 80) = 150
13 . t^1/4
14 . r^3/5
That's all I know sorry 'w' I'm only in 6th grade- lol
-56;+4
56 oopposite is -56
-(-4)=+4
2×2 + 8x + 26 =0
4 + 8x + 26 =0
4 + 26 = 0-8x
30 = 8x
divide both sides by th coefficient of x
30
=<em>3.75</em>
