Ivy randomly surveys students in her school to learn about mobile phone password use. of 25 respondents 14 use a password. based on ivy's data how many of the 275 students in her school would be expected to use a password?

Out of 25 respondents 14 use a password: 14/25

x amount of students out of 275 use a password: x/275

Set both fractions equal to each other

14/25 = x/275

Cross multiply.

14(275) = 25(x)

3850 = 25x

Isolate the x. Note the equal sign. What you do to one side you do to the other.

25x/25 = 3850/25

x = 3850/25

x = 154

154 students out of 275 are expected to use a password

hope this helps

$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
