Multiply 3 to the first bracket then multiply 2 to the second bracket. 3(a+2b) + 2(3a+b) = 3a+6b+6a+2b= 9a+8b
You said ax + 3b = 2f
Subtract 3b from each side: ax = 2f - 3b
Divide each side by 'a' : x = (2f - 3b) / a

Answer:
$1.5b - $32.76 = $292.74
Step-by-step explanation:
Profit = total revenue - total cost
total revenue = price per unit x total unit of bracelet sold
total revenue = $1.50 x b = $1.50b
b = total units of bracelets sold
total cost = $32.76
$1.5b - $32.76 = $292.74
