Chapter 1.5, Problem 6STP

In golf, there is a number of strokes assigned to each hole, called the par for that hole. If you get the ball in the hole in fewer strokes than par, you are under par for the hole. If it takes you more strokes than the par, you are over par for the hole. On the first 9 holes of golf, Avery had a par, 1 over par, 2 under par, another par, 1 under par, 1 over par, 3 over par, 2 under par, and I under par.

a. What addition expression would represent all 9 holes?

b. What is Avery’s score relative to par?

To determine

To calculate: In golf, there is a number of strokes assigned to each hole, called the par for that hole. If you get the ball in the hole in fewer strokes than par, you are under par for the hole. If it takes you more strokes than the par, you are over par for the hole. On the first 9 holes of golf, Avery had a par, 1 over par, 2 under par, another par, 1 under par, 1 over par, 3 over par, 2 under par, and 1 under par. What addition expression would represent all 9 holes?

Answer to Problem 6STP

  $=x-1$

Explanation of Solution

Given information: Let Par = $x$ , $t$ under par = $x-t$ and $t$ over par = $x+t$ .

Now we add all Avery's score

if we add a par, 1 over par, 2 under par, another par, 1 under par, 1 over par, 3 over par, 2 under par, and 1 under par , we get one under par

so, Avery's average score = $x-1$

Answer to Problem 6STP

Avery's score relative to par is one under par.

Explanation of Solution

if we add a par, 1 over par, 2 under par, another par, 1 under par, 1 over par, 3 over par, 2 under par, and 1 under par , we get one under par

so, Avery's average score = $x-1$

Avery's score relative to par is one under par.
