To solve this, you just have to multiply the percentage with the number.

I can show and guide you through the first, and then the second, to make sure you understand it.

$$0.1  \times 25000 = 2500$$

iwillrektyou · Answer

So, she has invested $2,500 in the stock when she had $25,000

Do you think you can do the second?

Right

campbell_st · Answer

do it this way... 

let x be the investment at 10% profit

and then (25000 - x) is the investment at 5% loss

and you know the overall result is $700

so 

700 = 0.1x - 0.05(25000 - x) 

collect like terms and solve for x

x=13000

campbell_st · Answer

correct so the investment that made 10% was $13000

leaving $12000 with a loss of 5%

10% of $13000 = $1300
5$ of $12000 = $600

so

1300 - 600 = $700
