if you sell x pounds of cake at $0.25 per pound how many dollars is that ? can you write down what formula you use?
Would the formula be \[$0.25x\]
yes. They say the number of pounds for each type of cake is the same. that means if you sold x pounds of the first type (at $0.25 per pound) you also sold x pounds of the the other two types. what is the formula for the dollars from all 3 types of cake?
If I add: 0.25+0.30+0.35=0.90 Which I think will be 0.90x.
I would write it as 0.25x+0.30x+0.35x = total dollars then factor out the x (0.25+0.30+0.35)x = total dollars simplify 0.90 x = total dollars the tell you the total dollars is 36 so you can solve for x 0.90 x = 36 the question asks for the total pounds sold, which is the 3x (x for each type of cake)
If I solve for 0.90x=36, I get x=40.
yes the question asks for the total pounds sold, which is the 3x (x for each type of cake)
So are you saying 40 times 3?
if you sell x pounds of cake 1 and x pounds of cake 2 and x pounds of cake 3, and x is 40 how many pounds did you sell?
Its 36 pounds right?
where did you get 36 from? you figured out up above that x=40 (and x is the number of pounds of cake 1 you sold) you also sold x pounds of cake 2 and x pounds of cake 3
I got 36 from doing: 0.25*40 = 10 0.30*40 = 12 0.35*40 = 14 10+12+14=36 I just substituted 0.25x, 0.30x, 0.35x (in which x=40). I added and I got 36.
10, 12 and 14 are the dollars you get from selling 40 pounds of each cake and yes, the dollars add up to 36 (like the problem tells you) The question they are asking is how many total pounds of cake did you sell?
Is it 120?
yes, you sold 40+40+40 pounds of cake
Thank you so much :)
