Jacqueline is buying grapes and apples from the Walmart produce section. Grapes are $3 per pound and apples are $4 per pound. Jacqueline's mother gave her $20 to spend. To determine the combinations of grapes and apples that she can afford to purchase,
Jacqueline wrote the inequality 3x+4y<20 .
Define the variables Jacqueline used based on the context.
Let x represent
Let y represent
Explain why the inequality sign s makes sense in this context.
Graph the inequality 3x+4y< 20.
The ordered pair (3,-4) is a solution to the inequality 3x + 4y s 20. Explain why this is not a viable solution in the context of buying grapes and apples.
The ordered pair (4,2) is a point on the boundary line. Explain what the ordered pair represents in the situation.
