sineoko [7]
Since p is in thousands, let p = 1800.

T(1800) = -496 + 70.17ln(1800)
T(1800) \approx 29.962...
1995 + T(1800) \approx 2025

So, in the year 2025, USA will surpass 1 800 000 in the population.

Last year at a certain high school, there were 50 boys on the honor roll and 100 girls
Sedbober [7]

there were 145 boys on the honor role and 60 girls equally given a total number of 205. This year, the number of boys decreased by 20% = 0.2*145=29

145-29=116

116 is this year number of boys on honor role

For girls.

=0.25*60=15

60-15=45

45 is this year number of girls on honor role.

Total number of students on honor role this year is 116+45 =161

Percentage of decrease = 1 -(161/205)*100% =( 1-0.785)*100

= 0.215*100

= 21.5%
