The commission is 5% on everything she sells
If she sold $1650.00
First you have to find her commission
100%=1650
5%=x
100•x=1650•5
100•x=8250
—— ———
100 100
x=82.5(this is her commission)
Now you have to add $82.5 to total she earns in the week.
$400.00+ $82.5 = $482.5
The Vanessa’s total pay last week was $482.5
Answer:
7x+9
Step-by-step explanation:
f(x)=7x-5
g(x)=x+2
f[g(x)]= Substitute g(x) in for x in the function f(x)
=7(g(x))-5
= 7( x+2) - 5
Distribute
= 7x+14 - 5
Combine like terms
=7x +9
