Answer:
The total cost in dollars, y = $7n.
Step-by-step explanation:
a) Data and Calculations:
Price of hot dogs = $2,75 each
Price of drinks = $1.50 each
Cost of hot dogs bought by one person = 2*2.75 = 5.5
Cost of drinks bought by one person = 1.50
Number of people in a group = n
y = total cost in dollars
y= n($5.5 + 1.50)
y = n * $7
y = $7n
b) Each person's purchase of hot dogs will cost $5.5 (2*2.75). When the cost of hot dogs per person is added to the cost of drinks per person, we have $7 ($5.50 + 1.50). This implies each person will consume hot dogs and drinks worth $7. The total cost will then be $7 multiplied by n, the number of people ($7n).
