Answer: $450
Step-by-step explanation:
We can form an equation representing the problem. The question is essentially asking 60% of what is equal to $270. If we define that what as a variable 'x', we get the following:


Multiply both sides by 100:


Divide both sides by 60 to solve for the value of 'x':

Answer is 450 bucks
We can check this answer by taking 60% of $450. In principal, this should return the discount of $270.

Yup, it checks out
Step-by-step explanation:
200÷100×40÷100× x = 40÷100 × y
2×0.4 × x = 0.4 × y
2x = y
x = y × 1÷2
x = y × 50%
