Please help asap, I'm so confused lol.
Sladkaya [172]

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:

\frac{60}{100} *x=270

\frac{60x}{100} =270

Multiply both sides by 100:

\frac{60x}{100} *100=270*100

60x=27,000

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

x=\frac{27,000}{60} =450

Answer is 450 bucks

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

\frac{60}{100} *450=270

Yup, it checks out
