Answer:Sheila makes $65 per day.
Kandice makes $15 per day.
Step-by-step explanation:
Let x represent the amount of money that Sheila makes per day.
Let y represent the amount of money that Kandice makes per day.
Sheila makes $50 more a day than Kandice. This means that
x = y + 50
Kandice has to work twenty days to make same as Sheila makes in fifteen days. This means that
15x = 20y - - - - - - - - - - -1
Substituting x = y + 15 into equation 1, it becomes
15(y + 15) = 20y
15y + 75 = 20y
20y - 15y = 75
5y = 75
y = $15
x = y + 50 = 15 + 50
x = $65
