We should find the mean number of the tests. 
This would be done like: (23+24+25)/3  = 24

After that, you should find the percentage or fraction like this 24/50
Then use the fraction as an estimate like this:

(24/50) * 3250 = 1560

The correct answer is 1560.

Solving one-step inequalities by multiplying/dividing<br><img src="https://tex.z-dn.net/?f=14v%20%5Cleqslant%2014" id="TexFormul
liubo4ka [24]

Answer: v <= 1


Step-by-step explanation:

When you have a variable by a number, you do the opposite of multiplying, so you divide

Since there's only 14v you divide 14 from itself leaving just the variable

14 ÷ 14 = 1

You repeat this and divide on the other side

14 ÷ 14 = 1

Since you arent dividing by a negative on both sides, the arrow stays the same

v <= 1

Hope this helps!
