The total cost for 9 bracelets, including shipping was $72. The shipping charge was $9. Define your variable and write an equation that models the cost of each bracelet.4. Use the equation you have written above determine the cost for each bracelet. Show the algebraic steps that it takes to find the answer. Provide your conclusion.

Answer:a) Equation: 9x+9 = 72b) x =7Step-by-step explanation:The total cost of 9 bracelets = $72Shipping charge = $9a) Define your variable and write an equation that models the cost of each bracelet.Let x be the cost of one bracelet, the equation will be9x + 9 = 72As 9 bracelets were there and the shipping cost was 9 and total cost was 72.b) Use the equation you have written above determine the cost for each bracelet. Show the algebraic steps that it takes to find the answer. Now solving the equation to find the value of x that represent cost of each bracelet9x + 9 = 72Adding -9 on both sides9x +9 -9 = 72 -99x = 63Dividing both sides by 99x/9 = 63/9x = 7The value of x=7 so, the cost of each bracelet is $7c) Provide your conclusion.So, each bracelet was of cost $7 and $9 was the shipping charge. so, the total cost is $72.We would check whether our equation is satisfied.9x+ 9 = 729(7) + 9 = 7263 + 9 = 7272 = 72The equation is satisfied.
