522

Step-by-step explanation:

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

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

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

60% of 870 = $\frac{60}{100}$ × $\frac{870}{1}$ $\frac{60}{100}$ × $\frac{870}{1} = \frac{52200}{100}$ $\frac{52200}{100} = \frac{522}{1} = 522$

I hope this helps!
