Answer:
After 17 hours there will be about 143 bacteria.
Explanation:
Given that in a lab experiment, 80 bacteria are placed in a petri dish, and the conditions are such that the number of bacteria is able to double every 19 hours, to determine how many bacteria would there be after 17 hours, to the nearest whole number, the following calculation must be performed:
80 x ((2/19) x 17) = X
80 x (0.1052 x 17) = X
80 x 1.7894 = X
143.15 = X
Thus, after 17 hours there will be about 143 bacteria.
