The number of students at marita’s school decreased to 98% of last year’s number. currently, there are 1,170 students. how many students were there last year?

  1194 students last year

Step-by-step explanation:

The problem statement tells us ...

  98% × (students last year) = 1170

Dividing by 98%, we get ...

  1170/0.98 = (students last year) = 1193.88 ≈ 1194

___

Check

1170/1194 = 0.979899... ≈ 0.98 = 98%

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)
