Question

Brittney has twice as much money as Sun. Together, they have $60. Let x represent the amount of money Sun has. What expression represents the amount of money Brittney has? What expression represents the amount of money that Brittney and Sun have together? What is the equation described in this problem?

Answer 1

x + x2 = 60

Explanation:

if Suns money is x

x + something = 60 --- their money together

if Brittney has 2 times the amount of money than Sun

x2 would mean sun´s money (x) times 2 = Brittney´s money

Hope this helps!!
