Answer:
65 grams
Step-by-step explanation:
The formula for an exponential sequence is ...
w(n) = (initial weight) × (1 - (decrease per use))^n . . . . for n uses
w(n) = 95·0.975^n . . . . . filling in the given numbers
Then for 15 uses, the weight is ...
w(15) = 95·0.975^15 ≈ 64.98 ≈ 65
The weight after 15 uses is about 65 grams.
