Answer 1

In this question, it is given that

Gary works no more than 9 hours on weekends and gets paid $10 per hour. He works whole-hour shifts. His pay, P, is a function of the number of hours he works, n.

For one hour, he will paid $10

For 2 hours, he will paid $20

For 3 hours, he will paid $30.

Similarly for n hours he will paid

`10n, 1\leq n \leq 9`

SO when n is 1, he will paid $10

When n is 9, he will paid $90.

Here range represents the range of P, which is

`[10,90]`
