Sandra bought 9 I teams from Walgreens for a total of $\$54$. Bottles of hand sanitizer cost $\$8$ each and face mask cost $\$3.50$ each. How many bottles of hand sanitizer did she buy?

Let's call the number of hand sanitizers x, 

That would make the number of face masks 9 - x. 

 

8(x) + 3.5(9 - x) = 54

4.5x + 31.5 = 54

4.5x = 22.5

x = 5. 

 

She bought 5 bottles of hand sanitizer. :))
