Answer: 19 + 14x ≤ 65
Explanation:
$19 is only added once because there is only one DVD purchased. $14 is added an unknown number of times, thus the variable X is included. We know that that the total number of dollars spent for both items is either less than or equal to 65. (Depending on your teacher, they may want you to write "19 + 14x < 65" if they want you to write the answer only for discrete numbers).
The answer is that it's a right triangle. One angle is 90°
The answer in this question is $8,175 the solution to get the answer is;
7.5% X $31,000 = $2,325
The amount that exceeds the 7.5% threshold is $10,500 - $2,325 = $8,175
