Answer:
B) 5 weeks
Step-by-step explanation:
We need to put each person in an equation where w is weeks and t is time:
50 + 15w = t
75 + 10w = t
Because we are calculating when they are the same, they can be equal to each other:
50 + 15w = 75 + 10w
Move the two integer values to one side (don't forget to change the operation to its opposite counterpart):
15w = 75 - 50 + 10w
Move the 10w value over to the other side.
15w - 10w = 75 - 50
Subtract like normal:
5w = 25
Cancel down by dividing both sides by 5:
[tex]\frac{5w}{5} = \frac{25}{5}[/tex]
This simplifies to:
w = 5
Meaning that it will take 5 weeks to have the same amount, so the answer is B.
Hope this helps!
