I think the Answer is 76 in^2
Hope this helps
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........
80*4=320
89*4=356
This is the range of the addition of all 4 scores.
99+80+70=249
320-249= 71
356-249= 107
[71, 100] would be the answer, unless you can get extra credit on the final.
5.834 x 10 to the power of -1
-- For just a minute, make it an Equality . . . y = x + 2 .
-- Graph the Equality. That graph is a straight line.
-- The INequality says that 'y' is LESS than x+2,
and THAT's everything UNDER the line.
(But not the points on the line itself.)
