At a restaurant, brandy paid twice as much as katie, and katie paid $3 more than stephanie. if the total combined amount they paid was $56, how much did katie pay? a. $12.50 b. $13.00 c. $14.00 d. $14.75 i need the answer asap

Let the amount that Brandy paid be b, the amount that Katie paid be k, and the amount that Stephanie paid be s.

b=2k
s=k+3
b+s+k=56

Substituting and doing the equation only in terms of k, we get:

2k+(k+3)+k=56
4k+3=56
4k=53
k=13.25
Katie paid $13.25.
Hope this helps!
