Consider below info to be a table:
AMOUNT OF BACTERIA
TIME - AMOUNT
1PM - 10gms
4PM - x gms
7PM - 19.6 gms
Data for a certain biology experiment are given in the table above. If the amount of bacteria present increased by the same factor during each of the two 3-hour periods shown, how many grams of bacteria were present at 4PM ?
Choose the correct choice from the following options
A) 12.0  B) 13.0  C) 12.2  D) 12.3  E) 12.4
let say the factor is x, the at 7PM quantity = 10 (i.e. quantity @1PM)* x^2 =19.6 =&gt; x^2 =1.96 or x = 1.3 =&gt; @4PM quantity = 10x =10*1.3=
