Declaration
Let x = number of times he saved 75 dollars.
Let y = number of times he saved 150 dollars
Equations
75*x + 150*y = 825 (1)
x + y = 8 (2)
Solve
Multiply 2 by 75
75x + 150y = 825
75x + 75y = 600 (3) Subtract (3) from (2)
75y = 225 Divide by 75
y = 225/75
y = 3
Therefore x = 8 - 3 =5
Conclusion
Be very careful what you conclude from this
x = the number of 75 dollars saved. The total for 75 dollars * 5 = 375
y = the number of 150 dollars saved. The total for 150 dollars * 3 = 450 Add
Total 825
