On a recent survey, 40% of those surveyed indicated that they preferred biking to hiking. a. If 280 people preferred biking, how many people were surveyed?

b. How many people preferred hiking?

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6

i don't even know how to read that, ill try to do it if you translate it into english.
