Question

Fifty students are trying to raise at least $12,500 for a class trip. They have already raised $1,250. Which inequality below could you use to find out how much each student should raise, on average, to meet their goal.

Answer 1

Hint:

( 12500 - 1250 ) / 50

Answer:

Each student should raise $225.

Answer 2

Answer:

$225.00

Step-by-step explanation:

Hello!

First of all, lets review the information given in this problem..

We know that 50 students are participating.

We also know that they are trying to raise at least $12,500.

Lastly, they said they had already raised $1,250.

Now, what do you need to find? We need to find which inequality could you use to find out how much each student should raise, on average, to meet their goal.

Lets start the problem...

Let  x  be the average amount that each person raises.

Since there are 50  students, the total amount that they raise will be the average amount for each times the number of students. This becomes:  50x

Take this amount and add to it the amount that they have already earned:  50x + 1250.

Since you want to raise at least 12500, you have this equation:  50x + 1250  ≥  12500

50x + 1250  ≥  12500

Subtract 1250 from both sides:

=> 50x  ≥  11250

Divide both sides by 50:

=> x  ≥  225

So, the average amount left to earn is at least $225.00.

I hope this helped you. Have a great day :)
