Answer:
0.116
Step-by-step explanation:

<span>How fast (in miles per hour) did he drive the first 3 hours? "He drove 56mph the first 3 hours."
Explain how you got your answer. "I got my answer by divding the miles he drove (168) by how many hours it took (3) to get 56."
If he continues to drive at that rate, how many hours will it take him to go the 280 more miles? "It will take him 5 more hours."
Explain how you got your answer. "I divided the miles he needs to travel (280) by the mph he would be going (56)."</span>
75+d=110 subtract 75 from both sides
d=$35
So she needs to deposit at least $35 to be able to pay the electric bill.
Answer:
The answer to the question is -16.
14000+7x=35x (x being the number of books) solve for x and you have your answer. 14000=35x-7x=28x therefore x=14000/28=500 so he needs to sell 500 books before he breaks even.
