Because for input=-2 there are more than one outputs. It means the this is not a function and it’s impossible to find a rule.
The discount is $1.19 unless you have to round up than it is $1.20. in order to solve this problem you would set up a proportion. So your proportion would be x over 7.99 = 15 over 100. Than you would cross multiply. 7.99*15=119.85. and 100*x=100x. than u divided both sides by a 100. than x= 1.19. which 1.19 is the discount.
C/4 - 2c = 5/4 - c/2......multiply everything by 4
c - 8c = 5 - 2c
-7c = 5 - 2c
-7c + 2c = 5
-5c = 5
c = -5/5 = -1
