Answer:
28 craft sticks
Step-by-step explanation:
Do 84/45
You get 1.8666
For every 1 pom pom you have 1.8666 craft sticks
Now you can multipy 15 by 1.8666 to get 28!
X =7.5
this is because you would cross multiply to get 12x=90. You would have to isolate the variable by dividing both sides by 12. that leaves you with x=7.5
