Answer:
60.07%
Step-by-step explanation:
Decrease: 16.78 - 6.70 = 10.08
% decrease:
10.08/16.78 × 100 = 60.07151371%
Answer:
60.1% decrease
Step-by-step explanation:
Let's say the percent decrease was x%. Now, we have the equation:
16.78 - x% * 16.78 = 6.70
x% is just x/100
16.78 * (1 - ) = 6.70
1 - = 6.70/16.78 ≈ 0.399
= 1 - 0.399 = 0.601
x = 60.1
Thus, the percent decrease is 60.1%.
Hope this helps!
