Answer:
- 1.30 is the growth factor per week
- 985 mold spores after 4 weeks
Step-by-step explanation:
The base of the exponential factor in a growth formula is the growth factor. Here, that is 1.30. It represents the multiplier of the number of spores each week.
Putting 4 into the formula, we find ...
f(4) = 345×1.30^4 ≈ 985 . . . . mold spores after 4 weeks
