Answer 1

Answer:

Cost of hard drive  =  $510 .

Step-by-step explanation:

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 .
