Question

In golf, the lower your score the better. Negative scores are best of all. Teri scored +1 on each of the first three holes at a nine-hole miniature golf course. Her goal is a total score of -9 or better after she has completed the final six holes. Let h represent the score Teri must avereage on each of the last six holes in order to meet her goal. Write a 2-step inequality you can use to find h

Answer 1

h ≤ - 2

Explanation:

Given :

Score on each of first 3 holes = +1

Total number of holes = 9

Target score - 9 or better ≤ - 9

Number of holes left = 9-3 = 6

h = average score on each of last 6 holes to meet target score ;

3 * (+1) + (number of holes left * average score) = target score

3 + (6 * h) ≤-9

3 + 6h ≤ - 9

6h ≤ - 9 - 3

6h ≤ - 12

h ≤ - 2
