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

x = 50*5

x = 250.

The current price of a four star meal is $250 per couple.

The correct answer is C.

once we distribute it it would become

150cw because of 15c  • 10w

and 80w^2 because of 8w • 10w
