Answer:
240
Explanation:
Melissa can decorate 2 cakes per hour.
If she were to work 5 hours a day, that'd be 10 cakes, because she can decorate 2 per hour, so 2*5=10. Now take the 10 cakes and multiply it by the 6 days- You're up to 60 cakes per week. Lastly, take the 60 cakes per week and multiply *that* by 4. 60*4=240 cakes in four weeks.
