Athena purchased a chain for $5 and sold it for $ 15, her profit for each chain is $15-$5. So for 2 chains, her net profit = 2*(15-5)
She also purchased bracelets for $8 and sold them for $9, her profit for each chain is $9-$8 . So for three 3 bracelets, her net profit = 3*(9-8)
Net profit from chains = 2*(15-5) or 2*15 - 2*5 (distributive property)
Net profit from chains = 2*10 or 10*2 (Commutative property)
Net profit from chains= $20
Net profit from bracelets = 3*(9-8) or 3*9 -3*8 (distributive property)
Net profit from bracelets = 3*1 or 1*3 (Commutative property)
Net profit from bracelets = $3

(2,0) is the correct answer
Answer:
Let AD=BC=x; then BD = 3-x.
Step-by-step explanation:
Then in right triangle BDC the legs are 2 and 3-x and the hypotenuse is x. Use the Pythagorean Theorem to find the value of x.
Then in right triangle ABC the legs are AC and x and the hypotenuse is 3. Use the Pythagorean Theorem again to find the length of AC.
