Question

WILL MARK AS BRAINLIEST!!!!!!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.
1.She used the wrong coefficient for x in her inequality.
2.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.
3.She graphed a solution set that does not match her inequality.
4.The graph should have an open circle at 12.

Answer 1

Answer:

.She graphed a solution set that does not match her inequality

please mark as brainliest answer

Answer 2

Answer:

Option (1) and (3)

Step-by-step explanation:

She chose the coefficient of x as 150. It should be 1.50

Then the inequality will become,

$1.50x \geqslant 1800 \\ x \geqslant 1200$

Thus, the interval she chose from [12,16] is redundant as there's no upper bound to the inequality.
