Tom saves $48.50 a month which is the best estimate of how much he will save at the end of the year?

A.$300

B.$350

C.$400

D.$600

To estimate you round 48.5 up to 50

50 times 12=600

and 48.5 was rounded up so the answer is teh nnumber <600, but closest to 600

so 600 would be a good estimate=D

12 mohts in year so

48.5 times 12=$582 saved in a year
