Problema Solution
I think the answer in the book is a misprint:
Juan's salary increased by $200 is the same as twice his salary. Find his salary. The Answer from the book is $20
My Solution : s = salary
*s made greater by 200 is 2s Evaluate(s=200)
-> s+200=2s s+200=2s
-> s+200-200=2s-200 200+200=2(200)
-> s-2s=2s-2s-200 400=400
-> -s/-1=-200/-1 [s=200]
Answer provided by our tutors
let
s = Juan's salary
s + 200 = Juan's salary increased by $200
2s = twice Juan's salary
Juan's salary increased by $200 is the same as twice his salary:
s + 200 = 2s
by solving we find:
s = $200

Juan's salary before the increase was $200.
