Rita makes and sells necklaces. The materials to make each necklace cost $2.75. Last week she made 8 necklaces and
wants to make a total profit of $78. Using the equation 8(x+2.75)= 78, Rita determined that she needs to sell each necklace
for $7 to make a total profit of $78. Which error did Rita make?
Although she has the correct equation, she needs to sell each necklace for $12.50.
Although she has the correct solution, she should have used the equation 8(x-2.75) - 78.
The equation should be 8(x-2.75) - 78, and she needs to sell each necklace for $12.50.
The equation should be a (x-2.75) - 78, and she needs to sell each necklace for $75.25.
