John made 100 cookies on Wednesday, twice as many cookies as he did on Monday and Tuesday combined. On Monday, he made two more cookies than on Tuesday. Let Tuesday be represented by t. How many cookies did he make on Monday?
Let's write a formula to represent this story. So we know on Wednesday he made 100 cookies, so on one side of the = sign is 100. On the other side we have t (Tuesday) and t+2 (Monday). And we know we need to combine them, and then double that number. So (t+t+2) x 2 = 100. Now we solve for t. (2t+2) x 2 = 100 4t + 4 = 100 4t = 96 t = 24 So he made 24 cookies on Tuesday. 24+2 is 26. 26 cookies on Monday.
In the problem 4 x y +8 which do you do first? A) x+8 B) 4 + y
Follow PEMDAS. I'm looking at PEMDAS and I see we have multiplication and addition in our problem. So do we do M first or A first? M comes before A so we do M first. Then we have 4y + 8.
