Answer:

Amount of loan pay = $6.840 (Approx.)

Step-by-step explanation:

Given:

Amount of loan borrow = $4,500

Rate of interest = 15% = 0.15

Number of year = 3 year

Find:

Amount of loan pay

Computation:

Future value = Present value[1+r]ⁿ

Amount of loan pay = Amount of loan borrow[1+r]ⁿ

Amount of loan pay = 4,500[1+0.15]³

Amount of loan pay = 4,500[1.15]³

Amount of loan pay = 4,500[1.52]

Amount of loan pay = $6.840 (Approx.)

Please help me I am really confused.
Feliz [49]

Answer:

f(96) = 85

Step-by-step explanation:

f'(95) gives us the slop of 6, which can be used to estimate the increase

of the next number.

Ex) f(95) = 79 & f'(95) = 6 so

     f(96) = 79 + 6 = 85
