Art currently saves 15% of his income. If his annual income is $44200.00, how much more money would he be saving per month if he put aside 28% of his income instead?
a. $5746.00
b. $6895.00
C. $5171.00
d. $4309.50
Art is currently saving 15% of his annual income, so he is saving 0.15 * $44200 = $<<0.15*44200=6630>>6630.00 per year.
This amounts to $6630 / 12 = $<<6630/12=552.50>>552.50 per month.
If Art were to put aside 28% of his annual income instead, he would save 0.28 * $44200 = $<<0.28*44200=12376.00>>12376.00 per year.
This amounts to $12376 / 12 = $<<12376/12=1031.33>>1031.33 per month.
Therefore, Art would be saving an additional $1031.33 - $552.50 = $<<1031.33-552.50=478.83>>478.83 per month.
Rounded to the nearest cent, this is equivalent to $478.83.
Therefore, the correct option is:
d. $4309.50. Answer: \boxed{4309.50}.
