Answer:
<u>44 </u>students will ride on each bus.
Step-by-step explanation:
Given:
Mr. Shipley is in charge of a school trip.
317 students will go on the trip.
The school had seven buses and one van.
If the van can haul nine students.
Now, to find the number of students who will ride on each bus.
Total students who will go on trip = 317.
So, we deduct the nine students of van from total students.
Thus, there are 308 students remaining for riding on the seven buses.
Now, to get the number of students that will be riding on each bus we divide 308 remaining students by number of buses:
Therefore, 44 students will ride on each bus.
Given:
Total amount of Mingfa and her sister = $130
If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.
To find:
How much money does Mingfa actually have?
Solution:
Let, Mingfa have $x and her sister has $y initially. Then,
...(i)
If Mingfa amount increased by $10, then the new amount is equal to three times of as much money as her sister.
...(ii)
Substitute the value of x from (ii) in (i).
Divide both sides by 4.
Putting in (i), we get
Therefore, Mingfa have $95.
