To find out how many watercolor paintings Megan made in total over both weeks, you need to know how many she painted last week and then double that number for this week.
1. Assume the number of watercolor paintings she made last week is X.
2. This week, she made twice as many, which would be 2X.
Now, add the two amounts together for the total number of watercolor paintings:
Total watercolor paintings = X (last week) + 2X (this week) = 3X.
So, if you can find out how many watercolor paintings she made last week (X), you can easily calculate the total for both weeks by multiplying that number by 3.
If you have the number of paintings from last week, just plug it into the equation!
