The local library lends an average books per day = 68.24
We know there are 7 days in a week
To find the the average number of books lent to readers in a week, we multiply the number of days in a week by average number of books per day.
let x be the average number of books per week
x= 68.24 * 7
x= 477.68
The local library lends an average of 477.68 books to readers every week.
Answer:

Step-by-step explanation:
Put the given number in the formula and do the arithmetic. The value of "d" is given as 7, so you are evaluating the expression ...
duration = 0.07×7^(3/2) . . . . put 7 where "d" is in the expression
= 0.07×18.520 . . . . . . . . . . . . evaluate 7^(3/2)
= 1.2964 . . . . . . . . . . . . . . . . . do the multiplication
≈ 1.30 . . . . rounded to hundredth
