Please help me with the math problem. Part 1

Step-by-step explanation:

r:=interest rate =7%

p = unknown

Principle + interest = 4280

t = 1 year

Formula

Total = p*r*t + p

4280 = p*(1 + r*t)

4280 = p*(1 + 7/100 * 1)

4280 = p (1.07)

4280 / 1.07 = p

P = 4000

What this means is that if you loan out 4000 dollars for a year at 7%, you will get 280 dollars in return (plus of course your 4000). However in this day and age, try getting 7%.

The 100 dollar problem is the same thing. This time you have P and you want the total.

Total = p(1 + r*t)

Total = 100 (1 + 7/100 * 1

Total = 100 ( 1 + 0.07)

Total = 107

So the principle is given and the value of the investment after 1 year is 107 dollars.
