Step-by-step explanation:

Total amount of extra money needed to be raised

= $483.62 -$218.25

= $265.37

Since each student raises the same amount and there are 17 students, $265.37 would be shared equally amongst the 17 students.

Amount of money each student must raise

= $265.37 ÷17

= $15.61

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)

8 2/3 is the answer
