To determine the correct inequality, we need to analyze the given information.
From the statement, Paolo solved an inequality and graphed the solution on the number line. This means that he found a range of values that satisfied the inequality and represented this range on the number line.
Looking at the answer choices:
1) 2.1x < 8.4
2) 3.7x > 14.8
3) 4.9x > 19.6
4) 2.8x < 10.5
Paolo's graph represents a solution on the number line, which means he graphed a range of values that satisfy the inequality.
Looking at the inequality options:
1) 2.1x < 8.4: The range of values satisfying this inequality would be marked below 4 on the number line. However, none of the answer choices specify this.
2) 3.7x > 14.8: The range of values satisfying this inequality would be marked above 4 on the number line. However, none of the answer choices specify this either.
3) 4.9x > 19.6: The range of values satisfying this inequality would be marked above 4 on the number line. However, none of the answer choices specify this.
4) 2.8x < 10.5: This is the only option that would have the range of solutions marked below 4 on the number line, which aligns with Paolo's graph.
Therefore, Paolo solved the inequality 2.8x < 10.5.
