Let a=3/4 and b=1/5. if a*x=b, then what is x?

In general, any equation like (assuming ) is solved by

So, in your case, the solution is

Dividing by a fraction means to multiply by the inverse of that fraction:

$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
