+318 Jake and Don had the same amount of money at first. When Jake gave Don $36, 50% of the amount of money Jake had left was the same as 75% of what Don had left. How much did they have in total at first?
+37146 j = d Given
(j - 36) * .5 = (d+36) * .75 sub in red equation fo j
(d-36) * .5 = .75 d + 27
.5 d - 18 = .75 d + 27
.25 d = -45 obviously there is a problem in the wording of the question
IF it said this instead:
When DON gave JAKE $36, 50% of the amount of money Jake had left was the same as 75% of what Don had left.
THEN
(j+36) * 5 = (d-36) * .75
.5 d + 18 = .75d - 27
.25 d = 45
d = 180 dollars each to start = 360 total dollars
