Cost of each shirt bought by Brain = 14.50
Then
Cost of 2 shirts bought by Brain = 2 * 14.50
                                                    = 29
Cost of a pair of shoes = 29.99
Total amount spent by Brain before tax = 29 + 29.99
                                                               = 58.99
Percentage of sales tax that needs to be paid = 6%
Amount of sales tax that needs to be [paid = (6/100) * 58.99
                                                                     = 353.94/100
                                                                     = 3.54
So
the total amount spent by Brain including tax = 58.99 + 3.54
                                                                         = 62.53

The park formed like a rectangle so : 
Area = length × width 
Area = ( 9/10 ) × ( 4/5 )
Area = 9 × 4 / 10 × 5
Area = 9 × 2 × 2 / 5 × 5 × 2 
Area = 18 / 25 
 
        
             
        
        
        
For the answer to the question above, just <span>use similar triangles. 
</span>Here's the equations that I used.
<span>t/h = (x + t) / r </span>
<span>x + t = rt / h </span>
<span>x = rt / h - t 
I hope my answer helped you in your problem, Have a nice day</span>
