1. it takes carter 2/3 gallon of paint to cover 3 %
walls. how many walls will one gallon cover?
show your work

For this case, we propose a rule of three, since with \ frac {2} {3} of gallons it covers 3% of wall, then:

gallon --------> 3%

1 gallon -----------------------> x

Where the variable "x" represents what percentage of wall can be painted with 1 gallon of paint. So:

Thus, with 1 gallon of paint 4.5% of wall are painted.

4.5%

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

answer: y = -2.5x - 15

              (-6,0)
