Answer:
1%
Step-by-step explanation:
Interest gain would be 9880 - 9500 = 380 dollars
9500 * i * 4 yrs = 380
i = .01 or 1%
x = 30
9-x/5=3
Subtract 9 from each side
9-9-x/5=3-9
-x/5 = -6
Multiply each side by -5
-x/5 *-5 = -6*-5
C and D I think??? Could be wrong. But definitely D is one of them.
9.8
