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 not to exceed $150?

A) $71,26

B) 84.207

Step-by-step explanation:

For the part A as the resident has use 40.000 gallons we need to divide that number in 741

=40.000/741=53,98

Thats the quantity of portions and every portion is $1,32 than we multiply

=53,98*1,32

=$71,26 (the bill for the resident)

For the part B you have $150 for the bill and every portion price is $1,32 than first we need to know how many portions the custumer can buy

=150/1,32

=113,64 portions

And every portion has 741 gallons, then we multiply to find the total gallons

=113,64*741

=84.207

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
