Write a function rule for finding the amount of daily pay, p, in the following situation: A bus driver gets paid $100 each day plus $0.20 per kilometer, k.
A. 100 = 0.20 × k
B. p = 0.20 × 100 × k
C. p = 0.20k + 100
D. 0.20k = 100 + p
The correct answer is C.
The function rule for finding the amount of daily pay, p, is: p = 0.20k + 100
This is because the bus driver gets paid $100 each day (a constant amount) plus $0.20 per kilometer (a variable amount that depends on the distance driven, represented by k). So we add these two amounts together to get the total daily pay, which is represented by the function rule.
