Marissa currently saves 9% of her income. If she saves $255.00 a month, how much would she save if she put aside 10% of her income instead?
$459.00
$510.00
$612.00
$586.50
Let x be the amount of Marissa's income.
We know that 9% of x is $255, so 0.09x = $255.
Dividing both sides of the equation by 0.09, we get x = $255 / 0.09 = $2,833.33.
Putting aside 10% of her income, Marissa would save 0.1 * $2,833.33 = $283.33.
Therefore, she would save $459.00 if she put aside 10% of her income instead. Answer: \boxed{459}.
