Ruth has $21,000 to invest in 2stocks. she wants to invest twice as much in stock(A) as in stock (B). How much should she invest in each stock?

Question

for answer a i got 14,000 and and for b i got 7,000 i just want to know is it correct

Answer 1

Looks good to me. 

 

It's not always easy to check your answer in math, but in this case it is: 14k + 7k = 21k, so she's definitely investing the amount she wanted to invest, and 14k is twice as large as 7k, so she's got twice as much going to Stock A.

 

Nicely done.
