Hi, please teach me how to solve the following math question.
Lisa had $37.5 more than Beth.If Lisa gave Beth $49.5,Beth would have 4 times as Lisa. How much do they have altogether?
@Loh Jane,
Let L be the amount Lisa has and B the amount Beth has.
Quote:Lisa had $37.5 more than Beth.
L = 37.5 + B
Quote:If Lisa gave Beth $49.5,Beth would have 4 times as Lisa.
B + 49.5 = 4 x (L-49.5)
Solve those two equations for L and B, then add them together to get the answer.
