Answer:
(2, 4)
Step-by-step explanation:
The only point that satisfies the inequality is (2, 4).
(0, 5) : -0^2 +5 = 5 . . . . . not > 5
(1, 3) : -1^2 +5 = 4 . . . . . . 3 is not > 4
(2, 4) : -2^2 +5 = 1 . . . . . . 4 is greater than 1, so this point is in the solution set.
It should be $92.00
80 • .15 = 12
so 15% of the total ($80) is 12.
add the 12 to the total 80+12= $92
