The money Debra has is $ 316.66
Solution:
Let the amount with Debra be "x"
Let the amount with Sherry be "y"
Given that Debra and Sherry have 475 in total
Amount with Debra + Amount with Sherry = 475
x + y = 475 -------- eqn 1
Debra has twice as much money as sherry
Amount with Debra = 2(amount with sherry)
x = 2y ------- eqn 2
Let us solve eqn 1 and eqn 2
Substitute eqn 2 in eqn 1
2y + y = 475
3y = 475
Divide both sides of equation by 3
y = 158.33
Substitute y = 158.33 in eqn 2
x = 2(158.33)
x = 316.66
Thus Debra has $ 316.66
