Answer:
Lauren has 30 jellybeans
Explanation:
Let x - Lauren
Let y = Haley
=
Cross multiply
8x + 3y
x = y - 50 Substitute y - 50 into the equation above for x
8(y -50) = 3y
8y -400 = 3y Subtract 8y from both sides
-400 = -5y Divide both sides by -5
80 = y This is Haley's jellybeans
x = y = 50
x = 80 - 50
x = 30 This is Lauren's jellybeans.
