Question

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

Answer 1

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!
