Answer 1

The answer is letter D which is 90.5%. To come with the answer you need to add the cost of new computer which is $399 and the computer memory which is $42 with the total amount of $441. Then you $399 by $441 and multiple by 100%. 

Solution:

= $399 + $42

= $441

=$399/$441 x 100%

=.9048 x 100%

= 90.48% or 90.50%
