100 muffins, and 2 in each packages. Therefore, there are 50 packages. However, at the end, there are 12 left, so there must have been 6 packages left. (12/2) 50-6=44. 44*2=88 so 88 muffins were bought.
Answer:
w=9x+4
Step-by-step explanation:
2(3x-3+w)=12x+2
6x-6+2w=12x+2
subtract 6x for both sides
-6+2w=18x+2
add 6 for both sides
2w=18x+8
Divide by 2 to find w
w=9x+4
