## breja 2 years ago Elena buys several shares of stock at \$28 per share and sells them at \$24.50 per share. What is the percent of decrease in the price of the stock

1. Mashy

do you know how to take percentage?

2. breja

no @Mashy But im learning

3. Mashy

ok.. percentage is basically out of 100 for example. if i say i scored 9 of 10.. then if i wanna know what my percentage score is.. then all i have to do is how much would i score out of 100.. and taht comes out to 90.. so 90 percentage.. is that clear?

4. breja

yea

5. Mashy

if i tell you.. i scored 4 out of 5.. whats my percentage score?

6. breja

0.2?

7. breja

8. Mashy

you do the cross multiplication 4 --- 5 ? --- 100 4 X 100 / 5.. how much does that yeild?

9. breja

80?

@Mashy

11. Mashy

perfect.. so thats how you do cross multiplication.. let me give you one more i i say.. i scored 50% percent.. how much did i score out of 25

12. breja

ohh i see where you going okay now 24.5*100/28 right

13. Mashy

no.. the question is .. what is the percentage DECREASE??.. so first find the decrease.. then find the percentage decrease!

14. breja

ohh okay

15. breja

idk

16. Mashy

tell me how much is the decrease?

17. breja

The difference is \$3.50. The percent decrease is therefore the difference divided by the original price: (3.50/28) x 100% = 12.5%???

18. Mashy

oh.. i love you :D.. correct!!

19. breja
