A friend asks you to think of a number, double it, and then add 4. Write an algebraic expression using the variable x to describe your friend’s directions. Then find the value of the expression if the number you think of is 3

Step-by-step explanation:

x= the number

2x+4

3= x

2(3)+4=

6+4= 10

$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
