Project #19785 - Math Extra credit

I need help with the following math questions for extra credit.


1.  At the farmer's market Mary purchased 100 pieces of fruit for $8.  If apples cost 5 cents, peaches cost 7 cents, and pears cost 9 cents how many more pears than apples did mary buy?

 

2.  After a rough day at the office, Mr. Wright was extremely short tempered and in no mood for more questions so when a solicitor came unexpectedly to see him that evening his temper began to grow shorter every instant.  "And how old are your children?" The agent asked.

     Mr. Wright replied acidly, "the square of Archie's age added to the square of Barbar's age added to          chester's age equals the square of chester's age.  When Archie is as old as Chester is now, chester will be four times as old as Archie is now and twice as old as Barbara is now"

     How old are the three children?

Please provide details
