22 ( total) - 10 ( what she has already) = 12 ( the amount she needs to buy)
If 1 hair and = $1
Than 12 multiplied by $1 = $12
So she needs to spend $12 in order to have 22 hair bands
F(x)=8x, because if you divide the money per hour you get the rate which is $8

Answer:
Step-by-step explanation:
3(x+4)-6=5x+5
distribute 3 through the parenthesis (3 times x + 3 times 4)=3x+12
3x+12-6=5x+5
subtract 12-6
3x+6=5x+5
Move the variable to the left and change the sign
3x-5x+6=5
collect like terms
3x-5x=5-6
-2x=5-6
divide both sides by -2
x=1/2
