Mrs. Pete wants the interior of her classroom to be repainted. On average, it costs $3.50 per square foot to paint a wall, and she has no more than $350 to spend. Model this scenario using a one-step inequality and let A be the unknown area. Which model can be used to find the largest area that can be repainted?(1 point) Responses 350A≥3.5 350 upper A greater-than-or-equal-to 3.5 3.5A>350 3.5 upper A greater than 350 3.5A≤350 3.5 upper A less-than-or-equal-to 350 3.5A<350
1 answer
The correct model is 3.5A≤350, which means that the total cost (350) is less than or equal to the cost of painting the entire area (3.5 multiplied by the area). This model can be used to find the largest possible area that can be repainted within the budget.
