Answer:
The correct answer is :
D. 700x + 375y = 15,000
x + y = 27
Step-by-step explanation:
1. Let's review the information given to answer the question correctly:
Budget for airline tickets = US$ 15,000
Number of employees attending the conference = 27
Price of business-class ticket = US$ 700
Price of economy-class ticket = US$ 375
2. Let's create a system of equations that models how many of each type of ticket the business should purchase.
x = Number of employees flying business-class
y = Number of employees flying economy-class
x + y = 27 (Number of employees attending the conference)
700x + 375y = 15,000 (Cost of employees flying business plus cost of employees flying economy equal to budget for buying the airline tickets)
