Step-by-step explanation:
Answer:
21) 778240
22) 10804
23) 4862.03
Step-by-step explanation:
20.
x is months. There are 12 months in an year, so for this problem use x = 12.
190( 2^12) = 778240
21.
The equation for growth is:
initial_amount((1 + percent_in_decimal_form)^years)
So now equation is 10280(1.01^5) = 10804
22. Use same equation as in #21.
4000 (1.05 ^ 4) = 4862.03
