Together with the interest of 15%, in 20 days an amount of 5445 dollars was received. What is the capital, and how much is the interest?

$5400

$45

Step-by-step explanation:

Interest = principal x interest rate x time

principal = p

interest rate = 15%

time = 20/365 = 0.054795

Interest = 5445 - p

5445 - p = 0.15 x p x  0.054795

5445 - p = 0.008219p

Collect like terms and solve for p

p = $5400

Interest = 5445 - 5400 = $45

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175
