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

Answer 1

Katie's share ---- x
Brandy --------- 2x
Steph-----------x-3

x + 2x + x-3 = 56

4x = 59
x = 14.75

Katie --- $14.75
Brandy --$29.50
Steph---$ 11.75

check:
14.75+29.50+11.75 = 56
All is good.
