. Artaud noticed that if he takes the opposite of his age and adds 39 he gets the number 28. How old is Artaud?

Question

Val rented a bicycle while she was on vacation. She paid a flat rental fee of $55.00, plus $8.50 each day. The total cost was $123. Write an equation you can use to find the number of days she rented the bicycle.

 

Answer 1

Assume that his age is x.  Then the opposite (or negative) of his age is -x.  If you add 39 to this, you get 28. As an equation, this would be written as:

 

-x + 39 = 28

 

Can you solve this equation for x?

Answer 2

$55 + 8.5X = 123

 

What does opposite of an age mean?
