Therefore, the solution is:

Step-by-step explanation:
We calculate the given integral. We use the substitution t = 7x.

Therefore, the solution is:

N can be 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 over or under the correct amount
"a rise of a quarter from last year" means the percentage went up by 25%
x = old value
x + 25% of x = x + 0.25x = 1.25x = new value = 0.25 since "1 in 4" means 1/4 = 0.25
So,
1.25x = 0.25
x = 0.25/1.25
x = 0.2
x = 2/10
x = 1/5
