Responses

y=0.5x+15
, where x
is the number of miles and y
is the total cost of the shuttle.
y is equal to 0 point 5 x plus 15, where x is the number of miles and y is the total cost of the shuttle.

y=15x+0.5
, where x
is the number of miles and y
is the total cost of the shuttle.
y is equal to 15 x plus 0 point 5 , where x is the number of miles and y is the total cost of the shuttle.

y=x+7.5
, where x
is the number of miles and y
is the total cost of the shuttle.
y is equal to x plus 7 point 5 , where x is the number of miles and y is the total cost of the shuttle.

y=7.5x
, where x
is the number of miles and y
is the total cost of the shuttle.
y is equal to 7 point 5 x , where x is the number of miles and y is the total cost of the shuttle.

Answer 1

y = 0.5x + 15, where x is miles and y is the total cost in dollars.

Explanation: $15 is the flat fee and $0.50 per mile adds 0.5x.
