Answer:
1.1772 is the single decal multiplier which should be used.
Step-by-step explanation:
Let the initial value be X.
After 8% increase, the value is =((100+8) /100) ×X = 1.08X.
Again after 9% increase, the final value is =((100+9) /100) ×1.08X =(1.09) ×(1.08) X =1.1772X.
This single decimal multiplier which should be used is 1.1772
