Write the constraint below as a linear inequality. A candidate will spend no less than $9100 on radio and TV advertising. Each radio spot costs $150 and each TV ad costs $720. Let x be the number of radio spots and let y be the number of TV ads. Choose the inequality that represents the constraint. A. 720x + 150y ≤ 9100 B. 150x + 720y ≥ 9100 C. 720x + 150y ≥ 9100 D. 150x + 720y ≤ 9100

A candidate has budgeted $8,100 to spend on radio and television advertising. A radio ad costs $162 per 30-second spot and a television ad costs $900 per 30-second spot. How many radio and television spots can the candidate purchase without exceeding the budget? Express your answer as a linear inequality with appropriate nonnegative restrictions and draw its graph. Let x be the number of radio spots and let y be the number of television spots. Choose the correct answer below. A. 162x + 900y > 8,100, x ≥ 0, y ≥ 0 B. 162x + 900y < 8,100, x ≥ 0, y ≥ 0 C. 162x + 900y ≥ 8,100, x ≥ 0, y ≥ 0 D. 162x + 900y ≤ 8,100, x ≥ 0, y ≥ 0

Use an inequality and the five-step process to solve each problem. Rhetoric Advertising is a directmail company. It determines that for a particular campaign, it can use any envelope with a fixed width of $3 \frac{1}{2}$ in. and an area of at least $17 \frac{1}{2}$ in $^{2} .$ Determine (in terms of an inequality) those lengths that will satisfy the company constraints.
