Blank=6
6 times 8 =48
because it is like 6 8s ok so 8+8+8+8+8+8=48
or
6+6+6+6+6+6+6+6=48
try it on paper and you will see I am right :)
D = {3,6,12,18)
R = {5,7,9,10}
It is not a function since for the 6 value of x, there are two different y outputs
It’s $132. 125 x 1.06 = 132, you multiply the first price by the number itself (1) and then the tax price (.06)
I believe it is discrete because you can only fill up to a certain point.
