Tim spends 500 minutes at the school.

Step-by-step explanation:

Given,

Time for lunch = 45 minutes

Time for study hall = 45 minutes

Total = 45+45 = 90 minutes

This represents 18% of the total minutes Tim spend at school.

Let,

x be the total minutes Tim spend at school.

18% of x = 90 minutes

[tex]\frac{18}{100}x=90\\\\0.18x=90[/tex]

Dividing both sides by 0.18

[tex]\frac{0.18x}{0.18}=\frac{90}{0.18}\\x=500[/tex]

Tim spends 500 minutes at the school.
