Hannah paid $1.50 each for programs to her play. She sold all but 20 of them for $3 each and made a profit of $15 total. How many programs did Hannah buy? How many did she sell?
Let x = the number of programs that Hannah bought. We use real numbers to see how we’d get the number that she sold: if she bought 100 programs and sold all but 20 of them, she would have sold 80 of them. We can see that 80 is 100 – 20, so the number sold would be x – 20.
Find and simplify ((f(x+h)-f(x))/h) for f(x)=x^2-3x+5
(h(2x+h-3))/h = 2x+h-3
