Answer:
216
Step-by-step explanation:
I think that it is 216 because if you add 18 and 10 you get 28 then multiply 28 by 12 then you get 336. Then you will find the area of the unshaded part which is 120. Then you will subtract 120 from 336 to get 216.

Your equation would be 8x - 4 = 60.
So,
8x - 4 = 60
+ 4 + 4
8x = 64
/8 /8
x = 8
x = 4 , y = ⅕
2x + 5y = 9 (1)
3x - 5y = 11 (2)
Add (1) and (2)
5x = 20
x = 4
Using (1), find y
2(4) + 5y = 9
5y = 1
y = ⅕
Interest = $10000 x 0.02 x 4 = $800
