Question

Solve the following word problems. You have a coupon for $50 off your camera purchase of $100 or more at Zeke's Camera World. Write a function relating a cameras purchase price after coupon,y,to the retail price,x.. Give the domain of this function. And if you use the coupon in problem 17, what is the minimum your camera purchase will cost (before tax)

Answer 1

Okay very well
So, y is the price after discount. x is the original price. and when x is greater than '100', 'y' is 50 less than x, otherwise not, right?

So, for x>100, y=x-50
for, x<100, y=x

that's your function^.
