Given :A Computer costs $849.75 and the hard drive is 61.3% of the total cost.
To find: What is a reasonable estimate for the cost of the hard drive .
Solution: we have given that
A computer costs = $849.75
According to question
Cost of hard drive = 61.3% of the total cost.
Cost of hard drive = 61.3% of $849.75
First we will estimate 61.3 % = 60 % .
Second we will estimate $849.75 = $ 850 .
Now, Cost of hard drive = 60% of $850
Cost of hard drive = $510 .
Therefore , Cost of hard drive = $510 .
