Answer:
G. Heather rented a hotel for $110 a night plus $18 a night for valet parking
Step-by-step explanation:
A proportional relationship is one that has a constant ratio between two variables
y/x = Constant
From the given options, the one with a proportional relationship is option G.
The amount at which Heather rented a hotel = $110
The amount he pays for valet parking = $18
The total amount Heather pays a night = $110 + $18 = $128
The amount she pays for 2 nights = 2 × $128 = $256
Therefore, we have;
From which we get;
y/x = 128/1 = 256/2 = 128 = Constant.
