I think it is -0.125.
It might also be 0.125
The equation representing the cost of the ride is R = $5 + $0.45dd.
<h3>What is flat fee? </h3>
The flat fee charged is the fixed cost. This cost remains constant regardless of the distance travelled. The additional fee is the variable cost. It increases with the distance travelled.
<h3> Derivation of the equation that represents cost of the ride.</h3>
Total cost = fixed cost + (variable cost x miles driven)
R = $5 + $0.45dd

Step-by-step explanation:
Answer:
7.2
Step-by-step explanation:
1. Natalie needed 40 minutes to get to school. In hours 40 minutes is 40/60= 2/3 hour (because there are 60 minutes in an hour). so her speed is 14.4/(2/3)= 14.4*3/2= 21.6 mph.
2. Britany needed 40+20= 60 min. 60 min= 1 hour. so she needed 1 hour her speed is 14,4/1= 14.4mph
3. The difference 21.6-14.4=7.2 is the answer .
This figure, I believe, is a triangular prism.
