Answer:
The correct answer is C.
Step-by-step explanation:
The price of a four-star meal, only $50 per couple decades ago, has since increased 400%.
This means that if the $50 per couple is 100%(decimal 1), the current price is 100%+400% = 500%(decimal 5). So we can solve a rule of three to find the current price of a four-star meal.
1 - 50
5 - x
.
The current price of a four star meal is $250 per couple.
The correct answer is C.
