Answer: 64 years old
Explanation:
Your grandma would be your dad's mom and since she is twice as old as your dad, she is 64. 32 x 2 = 64.
You can use a simultaneous equation - x + 7y=24 minus x-9y= -24 you end up with 16y = 48
Divide 48 by 16 and you get 3 is equal to y. Now put three into an equation eg, x + 21 = 24 it is now obvious that x = 3 as well as y = 3
Im gonna guess and say the right ones might be
A = AB or A'B'
B = CB or C'B'
D = CA or C'A'
Cus all equal the same side

or something
Every year $150 gains 12%, so every year you multiplythe value $150 times 1.12. So, after eight years the value will be:
$150 * 1.12 * 1.12 * 1.12 * 1.12 * 1.12 * 1.12 * 1.12 * 1.12 = $150 * (1.12)^8 = $ 371.39.
