Monique randomly surveyed 30 students from
Naily [24]

Answer:

522

Step-by-step explanation:

Find the percent of students in her class that have a dog or cat:

  1. Set up a proportion: \frac{18}{30} = \frac{x}{100}  
  2. Cross multiply, then divide: 18 × 100 = 1800, 1800 ÷ 30 = 60
  3. So, 60% have a dog or cat

Find 60% of the total amount of students in Monique's school:

  1. 60% of 870 = \frac{60}{100} × \frac{870}{1}  
  2. \frac{60}{100} × \frac{870}{1} = \frac{52200}{100}  
  3. \frac{52200}{100} = \frac{522}{1} = 522  

I hope this helps!
