Julia's number ---- x
Sam's number ---- x+88
give-away:
Sam now has .8(x+88) = .8x + 70.4
Julia now has .2(x+88) + x = 1.2x + 17.6
.8x + 70.4 = 2(1.2x + 17.6)
.8x + 70.4 = 2.4x + 35.2
35.2 = 1.6x
x = 22
Julia had 22 at the start and Sam had 110
check:
Sam gave 20% of 110 or 22 to Julia
So had 88 left and she now has 44
So Sam still has twice as many as Julia
My answer is correct.
Sam had 88 more muffins than Julia. He gave 20% of his muffins to
Julia. He then had twice as many muffins as Julia.
How many muffins did Sam have at first?
