Explanation:

Step1: Convert percentage to decimal

To find 80% of 85, we first convert 80% to a decimal. 80% is equivalent to $0.8$ (since $80\%=\frac{80}{100} = 0.8$).

Step2: Multiply the total number of seats by the decimal

We multiply the total number of seats (85) by 0.8. So the calculation is $85\times0.8$.
Calculating $85\times0.8$: $85\times0.8 = 68$.

Answer:

68
