So this problem says a painter was hired for a house renovation. The painter charges $0.5 per square meter and a fixed cost of $ which serves as his allowance for transportation. If the painter charged the client a total of 3 70 how many square meters was he able to paint? So if you look here we have 0.5 per square meter and the fixed cost of $60. We also have a total of 370. So let's go ahead and set up already. Question. Well we know we charge 0.5 per square meter. I will say 0.5 times are variable, which I'll give a for area We have a fixed cost of $60 so we add that onto the end 60 That equals a total of 370. Now we're going to go ahead and solve for a So if you like here we have a 60 here. 370 other side, let's go and subtract 60 from both sides. We end up with 0.5 times a Equals to 310. Now we can go ahead and divide both sides by 0. five air 0.5 at the end we just slept with a We have 3 10 over . that is equal to 620. So the amount of square meters he was able to paint with 620, which makes our answer answer. D Okay thank you for watching. I hope to solve the problem. Goodbye
