Use proportion to solve the following problem

the water rate for a city in north carolina is $1.32 per 741 gallons of water used.
a) what is the water bill if a resident of that city uses 40,000 gallons?
b) how many gallons of water can a customer use if the water bill is exceed $150?

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
