​

Answer 1

Answer:

compound interest formula

t

p ( 1+r/100)^

100000(1+7/100)³

=1,225,043

500,000 - 1,225,043 = 3,774,957

let the p be = x

x(1+5/100)2 = 3,774,957

Answer 2

Step-by-step explanation:

so we receive 500,000 at the end of 5 years

5000,00 = 100,000(1+0.0.7)^3+ x(1+0.05)^2

by solve this equation on calculator

you get

342399.7279
