Answer:
713 paint balls
Step-by-step explanation:
The inequality equation for the above question is given as:
$18 + $0.08 × b ≥ 75
Where b = number of paint balls
$18 + 0.08b ≥ 75
0.08b ≥ 75 - 18
0.08b≥ 57
b ≥ 58/0.08
b ≥ 712.5
b≥ 713 paint balls
Hence, Carolina would need to buy 713 paintballs along with the entrance fee to get the promotion.

Step-by-step explanation:
<u>Step 1: Define Systems</u>
a + 4b = -4
a + 10b = -16
<u>Step 2: Rewrite Systems</u>
a + 4b = -4
- Subtract 4b on both sides: a = -4 - 4b
<u>Step 3: Redefine Systems</u>
a = -4 - 4b
a + 10b = -16
<u>Step 4: Solve for </u><em><u>b</u></em>
<em>Substitution</em>
- Substitute in <em>a</em>: -4 - 4b + 10b = -16
- Combine like terms: -4 + 6b = -16
- Isolate <em>b</em> term: 6b = -12
- Isolate <em>b</em>: b = -2
<u>Step 5: Solve for </u><em><u>a</u></em>
- Define equation: a + 4b = -4
- Substitute in <em>b</em>: a + 4(-2) = -4
- Multiply: a - 8 = -4
- Isolate <em>a</em>: a = 4
