I think the answer is C. "He made a place value error when dividing. If he would have divided 1.09 by 8, he would have found the price of each individual pen.
Blank 1: 3
Blank 2: 27
Blank 3: 21
you have to distribute the three to everything inside the parenthesis, and because it's directly in front of the parenthesis it's being multiplied.
3(x - 9) = 3x - 27
Now you need to isolate the y, in this e ample you need to add 6 to both sides
the final equation should be:
y = 3x - 21
If you add the white and blue together then you have 25 and 25 is 50% of 50
The Answer is A... your welcome
