The text after the colon defines the missing word: she used clear, simple language anyone could follow. Lucid means clear and easy to understand, so it fits exactly.
Why the others miss: "Elaborate" means complicated — the opposite of simple. "Ambiguous" means unclear, which contradicts the sentence. "Tedious" means boring, which the text never suggests.
Subtract 3 from both sides: 5x = 25. Then divide by 5: x = 5. You can check it — 5(5) + 3 = 28. ✓
Why the others miss: 25 is the value of 5x, one step short of solving for x. The decimals come from dividing 28 (or 3) by 5 before clearing the +3 — handle the addition first, then the multiplier.
25% of $80 is $20, so the discount is $20. Subtract it from the original: $80 − $20 = $60. (Shortcut: paying 75% of $80 is 0.75 × 80 = $60.)
Why the others miss: $20 is only the discount, not the price you pay. $64 takes 20% off instead of 25%. $55 doesn't match either rate.
