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 x greater-than-or-equal-to 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.
A number line going from 6 to 16. A closed circle is at 12. Everything to the right of the circle is shaded.
What errors did she make? Select two options.
o She used the wrong coefficient for x in her inequality.
o She should have used the less than or equal to symbol instead of the greater than or equal to symbol.
o She interpreted the graph incorrectly.
o She graphed a solution set that does not match her inequality.
