Question

Anwita and her sister have $230 in total. Anwita has x dollars and her sister has 20

less than quadruple what Anwita has. How much more money does Anwita need to
have the same amount as her sister?

Answer 1

$130

Explanation:

x (the $ Anwita has) + y (the $ her sister has) = 230

y = 4x - 20

=> x+y=230 => x + 4x - 20 = 230

=> 5x - 20 = 230 => 5x = 250

=> x = 50

=> y = 180

the difference between 180 and 50 (180 - 50) is 130.

so, Anwita needs $130 more to have the same amount as her sister.
