So basically you start with $25 and then you can multiply 5✖️12 because there is 12 months in a year so then you take the product and multiply it again by 2 and finally you add it to $25.I’m not really good at math but I hope this helps :)
        
             
        
        
        
A= 3400t + 600 | given formula 
21000= 3400t + 600 | substitute the altitude into the formula 
20400 = 3400 | subtract 600 from both sides 
6 = t | divide both sides by 3400
6 minutes
        
             
        
        
        
It can be deduced that the triangles are similar because the three internal angles are equal for both triangles.
<h3>How to solve the triangle?</h3>
It should be noted that the triangles are similar because the three internal angles are equal. 
In this case, the ratio of the corresponding sides are equal and the corresponding angles are congruent. 
The width of the river will be:
300/80 = AB/50
AB = (300 × 50)/80
AB = 187.50 feet.
