Leonard and Marcus have saved up a total of $47. Leonard has saved three dollars less than 3/5 as much as Marcus, how much Marcus saved.
Let x be the amount Marcus saved.
Then Leonard saved (3/5)*x - 3.
The total saved is x + (3/5)*x - 3 = $47.
Combining like terms gives (8/5)*x - 3 = $47.
Adding 3 to both sides gives (8/5)*x = $50.
Multiplying by 5 gives 8x = $250.
Dividing by 8 gives x = $31.25.
Therefore, Marcus saved $31.25.
