The school band is selling candy to raise $1,800.00 to pay for their trip to a band festival. The band earns $1.50 from every box of candy sold. Kayla solved the inequality 150>1,800 to find the number of boxes the band must sell to meet their goal. She graphed her solution on a number line and interpreted the solution to mean the band will meet their goal if they sell fewer than 12 boxes.
What errors did she make? Check all that apply.
She used the wrong coefficient for x in her inequality.
She should have used the less than or equal to symbol instead of the greater than or equal to symbol.
She interpreted the graph incorrectly.
She graphed a solution set that does not match her inequality.
The graph should have an open circle at 12.
