63. grace bought a dress, d, that was 45% off the regular price, r.
a write an equation that represents this situation.
b the price of the dress before the 45% discount was $85.00.
after the discount, a 9% sales tax was added to the final sale
price. calculate the final cost of grace's desk. show how you
found your answer.

A.

r - (r x .45) = d (The discounted price of the dress.)

B.

85 - (85 x .45) = 46.75

Now to find the final cost.

46.75 + (46.75 x .09) ~ 50.96

The final price is $50.96.

Hope this helps!

If it does, it would help a lot if you make me brainliest.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
