Question

A painting company has determined that for every 115 square feet of wall space, one gallon of paint and eight hours of labor are required. The company charges $18 per hour of labor. Write a MATLAB function that has as input arguments: 1) an array with the square footage of each room to be painted, 2) price per gallon of paint. The program will print out to the screen, in complete sentences, the following information: the number of gallons of paint required & the cost of the paint, the hours of labor required & the labor charges, and the total cost of the paint job. For example: paintjob([400,500,360] ,22) Number of gallons = 11; total cost of paint = $242.00 Hours of labor = 88.0; labor cost = $1584.00 Total cost = $1826.00 Use fprintf to print the results. Do not use sum; use a for-loop to solve this problem.

Explanation / Answer

%PLEASE RATE, and if anyone copys answer , please Flag them

function paintjob(sqfootage,price)

% every 115sqft = 1gal paint && 8hr

hourRate=18; % cost per hour of labor

area=0;

for i=1:length(sqfootage)

area=area+sqfootage(i);

end

gal=ceil(area/115);% one gallon =115 sqft , round ups

hours=gal*8;% total hours

paintCost=price*gal;

LaborCost=hourRate*hours;

TotalCost=paintCost+LaborCost;

fprintf('Number of labor = %d; total cost of paint = $%.2f ',gal,paintCost);

fprintf('Hours of labor = %.1f; labor cost = $%.2f ',hours,LaborCost);

fprintf('Total cost = $%.2f ',TotalCost);
