We need to build a system of equations:

a + b + c = 127......(1)
b  - c = 13..............(2)
a - b - c = 41..........(3)

adding equations (1) and (3):-

2a = 168
a = 84   
Substituting for in equation (1)-
84 + b + c = 127
b   + c = 43...........(4)
Adding equations (2) and (4):-
2b = 56 

b = 28
Finally from equation (2)
c = 28-13 = 15

Answer is Country a had 84 points , b had 28 points and c had 15 points.

$100 is invested at 12% per year. If the amount is compounded annually, write the total amount after 2 years in exponential func
Sladkaya [172]

Answer:

A = $100(1.12)^2

Step-by-step explanation:

The standard formula for compound interest is given as;

A = P(1+r/n)^(nt) .....1

Where;

A = final amount/value

P = initial amount/value (principal)

r = rate yearly

n = number of times compounded yearly.

t = time of investment in years

For this case;

P = $100

t = 2years

n = 1

r = 12% = 0.12

Substituting the values, we have;

A = $100(1+0.12)^(2)

A = $100(1.12)^2
