= 1.2 x 10³ times .

(That's 1,200 times as many.)

Answer 2

Answer:

1221.2 times more

Step-by-step explanation:

number of bacteria last week = $2.25*10^2$

= $2.25*100$

= $225$

number of bacteria this week = $2.75*10^5$

= $2.75*100000$

= $275000$

$275000 - 225 = 274775$

$274775 / 225 = 1221.2$
