Line R
2x + 2y = 18
if we divide by 2 in both side
x + y = 9
Line M
x + y = 9
if x = 1, then y = 8
if x = 2, then y = 7
likewise you can find infinite pair answers for x and y
{12,15} {boys,girls} that's the ratio 12 boys and 15 girls/12to 15

Answer: (i) A = 2500 (
(ii) A =$ 4,974.47
Step-by-step explanation:'
The exponential function is given as :
A = P
Where :
A = amount
P = principal
r = rate %
n = number of years
substituting , the exponential function to model the situation becomes
A = 2500 (
(ii) when n = 20 , the Amount becomes
A = 2500(
A =$ 4,974.47
