d.24 is may the answer of it
S is 170 Q is 90 and R is 62
8 hot dog buns per package
number of packages is 30
therefore number of hot dog buns = 30 x 8 = 240
hope this helps :P
Step-by-step explanation:
10 x 2 = 20 (after 15 minutes) 9:15
20 x 2 = 40 (after 30 minutes)
40 x 2 = 80 (after 45 minutes)
80 x 2 = 160 (after 60 minutes) - 10:00
160 x 2 = 320 (after 75 minutes)
320 x 2 = 640 (after 90 minutes)
640 x 2 = 1280 (after 105 minutes) - 10:40
There will be 1280 bacteria in the dish at 10:40.
