Hi can you please help me with these math questions? I really need to know the answers.
21. Find the unit price for each option shown below. Round to the nearest cent when necessary. Indicate which option is the better buy.
Option I: 10 candy bars for $6.75
Option II: 12 candy bars for $7.25
22. Calculate the final price you would pay to buy a jacket that originally sells for $65, but is discounted by 40%, you also have to pay 5% sales tax.
23.Natalie picked 135 berries in 15 miniutes. If she continues picking at that rate, how long will it take her to pick 486 berries?
I have an answer but I don't know if its right: 15 X 486 / 135= 54
25. ( 42%= Football
33%= baseball
25%= soccer)
If 210 people said football was their favorite sport to watch, how many people were surveyed?

I think I got 21. 10/$6.75 = $1.48 12/$.25= $1.65 so option 1 is cheaper.
Then for 22 I got:
65 X 0.6 X 1.05=$40.95
65 X 0.6 X 1.05=$40.95
And then my answer for 25 is 210 by 42=5 1%=5 people 100% x 5 people=500
21. Does that make sense to you? Would you pay $1.48 each when you could get 10 for less than $7.00?
22. and 25. are correct.
22. and 25. are correct.
I don't even get number 22.
