Answer:
B and C
Step-by-step explanation:
This problem is pretty simple if you know how to do some multiplication. First, we should figure out how many hours she works per week. You can figure this out by dividing 60 by 3. This gets us 20.
Now that we know how many hours she works each week, we can figure out the rest of the problems.
A is incorrect because 4 x 20 =80.
B is correct because 7 x 20 is 140.
C is correct because we did this problem earlier to solve the others.
D is in correct because 5 x 5 = 25, which does not equal 20.
E is incorrect because 16 x 20 = 320
Sorry if I'm not very good at this, as this is my first time solving someone's question.
