If $520 is borrowed for 290 days at 2.15% simple annual interest, how much will be repaid at the end of 290 days?

Step-by-step explanation:

Formula for simple interest

where a = final amount

p = principal amount

r = annual interest rate

t = time in years

given p = 520,

r = 2.15/100

t = 290/365 (1 year = 365 days)

51-50

step-by-step explanation:

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
