The equation that would best describe the situation would be the first option. To solve this question, simply break down the question into sections and then use variables X and y to represent each of the things asked for in the problem. We know the following: 
X = no of tetra fish 
Y = no of goldfish
If there is twice as much goldfish than tetra fish, then it would be 2y.
X = 2Y. 
Then knowing what X and y represent, find the equation that gives the total cost of fish he bought, knowing that 1.50 is for a goldfish and 2.00 is for a tetra fish.
        
             
        
        
        
2500-700 = 1800
1800/5 = 360
The annual depreciation of the camera is $360.
        
             
        
        
        
No nickles = 2x and that of dimes = 7x so 2x = 350 get x and the no of dimes
so like 2x = 350 divide by 2 on both sides so x = 175 ... and no of dimes = 7*x = 7*175 = 1225
Hope it helps :)
