Answer:
$2 was the dollar gain for the stock XYZ
7.50
25% also equals 1/4 so divide 130.00 by 4 which equals 32.50
subtract 32.50 from 130.00 which equals the cost, 97.50
97.50 minus 90$ is 7.50, therefore that is the answer
A + b = 87
a = b - 11
b - 11 + b = 87
2b - 11 = 87
2b = 87 + 11
2b = 98
b = 98/2
b = 49 <===
a = b - 11
a = 49 - 11
a = 38 <===
6 times 12 is 72 so 14 times 12 would be 168 if that is what you are looking for. So for that y=168 :-)
