Fifty students are trying to raise at least $12,500 for a class trip. they have already raised $1,250. how much should each student raise, on average, in order to meet the goal? write and solve the two step inequality for this problem.

50t + 1,250 >= 12,500

On average, each student must raise at least $225.

Step-by-step explanation:

They are trying to raise "at least $12,500".

At least $12,500 means $12,500 or more.

The amount they raise must be greater than or equal to $12,500.

Each student must raise at least t.

There are 50 students, so combined, they will raise 50t.

They already have $1,250, so they will have a total of 50t + 1250.

The combined amount they raise must be greater than or equal to $12,500.

The equation is:

50t + 1,250 >= 12,500

Subtract 1250 from both sides.

50t >= 11,250

Divide both sides by 50:

t >= 225

On average, each student must raise at least $225.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
