Answer:
The nonpermissible replacement of the variable y is -3
Step-by-step explanation:
The nonpermissible replacement of the variable in a certain expression is the value of the variable that will make the denominator of the expression zero.
The expression 
has the denominator 
This denominator cannot be equal zero, thus,
I think it's 1/6. Because before school she drinks 1/4 then before lunch she drink 2/3 if 1/4 so you would multiply. 1*2=2. 4*3=12. So you get 2/12 or if you simplify, 1/6
1510*0.02=$30.20 which is larger than $20.00. 2%= 0.02
