Marie wants to buy an outfit that costs 89.00. She has 100 and doesn’t know if she has enough money after the sales tax is added on. if the sales tax is 8% does Marie have enough money to buy the outfit

Yes she does if you multiply 89.00 by the sales tax which is 0.08 you’ll get 7.12 then you add that to 89.00 which gives you 96.12 so yes she will have enough to buy the outfit

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
