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.

Answer:
Carla pays $21.4 for the dress with tax.
Step-by-step explanation:
Here we are given that :
Price of dress = $20
Sales tax = 7%
Price of dress with tax = $20 + 7% of 20
Price of dress with tax = 20+1.4 = 21.4
Price of dress with tax = $21.4
Carla pays $21.4 for the dress with tax.
