Question

The price of a​ four-star meal was ​$50 per couple decades​ ago, has since increased 300%. The current price of a​ four-star meal is which of the​ following?

A) A​ four-star meal is ​$100 because 3 x $50 = $150​, from which ​$50 is subtracted.

B) A​ four-star meal is ​$300 because 3 x $50 = $150​, which is multiplied by 2 because the price is per couple.

C) A​ four-star meal is ​$150 because 3 x $50 = $150.

D) A​ four-star meal is ​$400 because 3 x $50 = $150​, which is added to ​$50 and then multiplied by 2 because the price is per couple.

E) A​ four-star meal is ​$7,500 because 3 x $50 = $150​, which is multiplied by 50.

F) A​ four-star meal is ​$200 because 3 x $ 50 = $ 150​, which is added to ​$50.
