Pretty sure it is B.) It would be cheaper to return the car on time and pay the refueling cost.
The constant of proportionality is 5/9
y= kx where k is the constant of proportionality
y = 5/9 x
k = 5/9
To find how much Fiona makes per hour divide her earnings (y) by the number of hours worked (x).
42/3= $14 per hour
Phillip makes $12 per hour.
14-12 = 2
Fiona makes $2 more per hour tan Phillip
The right answer is Option A.
Step-by-step explanation:
Given,
Heart rate goal = I
Heart rate reserve = H
70% of H =
Resting heart rate = R
According to given statement,
70% of heart rate reserved is added to resting heart rate to calculate heart rate goal, therefore,
I = R + 0.7H
I=R+0.7H represents the given situation.
The right answer is Option A.
