We know that the domain is actually the number of rolls
that she gets because it is the input variable in the equation f (r) = 40 r + 26. The number of rolls that
she can get can never be a negative number nor a zero nor a decimal number.
However she can only get up to 10 rolls. Therefore the answer is:
all integers from 1 to 10, inclusive
Hello!
Let's check:
200 * 25% = 50
200 - 50 = 150
150 * 10% = 15
150 - 15 = 135
So, with the 25% and then an extra 10% off, the coat would cost $135.
200 * 35% = 70
200 - 70 = 130
So, Jenny's friend is incorrect, because that is not the same as a 35% discount.
