1. You decide to make and sell bracelets. The cost of your materials is $84. You charge $3.50 for each bracelet. a. Write a function that represents the profit P for selling b bracelets.

P=

2. You will break even when the cost of your materials equals your income. How many bracelets must you sell to break even?

You must sell bracelets to break even.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
