You pay 3.5% annual simple interest for 12 years on a loan, and you pay $1,512 in interest. How much is the principal?

Anika [276]

A = Pe^rt
Amount of interest paid = Principal*e^ (rate*time)
(The rate must be in decimal form)
3.15% / 100 = .0315

1,512 = P[e^(.0315*12)]
1,512 / e^(.0315*12) = P
1036.06 = P
$1036.06 was the Principal
** I left that value unrounded to the hundreds place because one doesn’t round with money. :)

Good luck!

Haruka hiked several kilometers in the morning. She hiked only 6 66 kilometers in the afternoon, which was 25 % 25%25, percent l

zmey [24]

Answer:

Harukah hiked for 14 km in all.

Step-by-step explanation:

We are given the following in the question:

Hike in afternoon = 6 km

Let Haruka hike x km in the morning.

We are given the relation:

$6 = x - 25\%(x) \\\\6 = x - \dfrac{25}{100}\times x\\\\6 = 0.75x\\\\x = \dfrac{6}{0.75}\\\\x = 8$
