Answer:
44 dollars
Step-by-step explanation:
28 minus 5 is 23
67 minus 23 is 44
-30-5x=-4x-6(5+4x)
First, you need to use the distributive property on the right to get -30-5x=-4x-30-24x
Then, you can add like terms to get -30-5x=-30-28x
Then, you can add 30 to both sides and add 5x to both sides to get 0=-23x
Finally, you divide both sides by -23 to get 0=x
%change=100(final-initial)/initial
%change=100(25-40)/40=-37.5%
So Denise received a discount of 37.5% off the regular price.
