The solution for the x-value in this set is -7≤x
Answer:
; 
Step-by-step explanation:
The inequality says the sum of x and 25 (written as x + 25) is less than (<) 75.
The inequality is written as: 
My work for solving the inequality is in the picture.
It’s both a relation and a function
Each year 107.2%increase of budget
first year 500 * 1.072 = 536
second year 536 * 1.072 = 574.592
third year 574.592 * 1.072 = 615.962624
..
..
sixth year 707.854392 * 1.072 = 758.819908
or you can just (1.072)^6 * 500 = 1.517639816659862 * 500 = 758.8199083299308
bingo........
