Answer:
18 Kilograms of Dough.
Step-by-step explanation:
If she prepares 6 kilograms of dough every hour she works, then 6 would be the unit rate. So, the equation would set up to 6 • x, x being the unknown amount of hours she worked. Since we know that she worked for 3 hours, we plug in 3 for the x, thus the equation would be 6 • 3. This comes to 18 kilograms.
