Question

On her math test, Anna is asked to write an inequality that fits the following situation:

Answer 1

3x+250-100×2x = 24.5x to 2nd power.

Got this same question earlier in the year.

Answer 2

Answer:

Yes, I can find Anna's mistake.She writes 250-2x  instead 2x-250 and correct inequality

$3x+100 < 2x-250$

Step-by-step explanation:

Let x be the number of candy pieces.

Three times the number of candy pieces=$3x$

John guess a number =$3x+100$

Twice the number of candy pieces=$2x$

Keisha guess a number=$2x-250$

We have to find Anna's mistake and write correct inequality

According to question

$3x+100 < 2x-250$

But Anna writes the inequality

$3x+100 < 250 -2x$

Yes, I can find Anna's mistake. She writes 250-2x instead of 2x-250 and correct inequality

$3x+100 < 2x-250$
