Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
3(2x - 1) - 11x ≤ -3x + 5
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Distributive Property Distribute 3: 6x - 3 - 11x ≤ -3x + 5
- [Subtraction] Combine like terms: -5x - 3 ≤ -3x + 5
- [Addition Property of Equality] Add 5x on both sides: -3 ≤ 2x + 5
- [Subtraction Property of Equality] Subtract 5 on both sides: -8 ≤ 2x
- [Division Property of Equality] Divide 2 on both sides: -4 ≤ x
- Rewrite: x ≥ -4
<em> Given that:</em> 100 copies = $3.10
<em>Find cost of 1 copy:</em>
1 copy = $3.10 ÷ 100 = $0.031
<em>Find the cost of 155 copies: </em>
155 copies = $0.031 x 155 = $4.81 (nearest hundredth)
Answer: $4.81
