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 less than 350

3.5A≤350
3.5 upper A less-than-or-equal-to 350

3.5A>350

1 answer

To model the scenario where Mrs. Pete wants to repaint her classroom walls with a total budget of $350, we know that the cost per square foot is $3.50. If we let \( A \) represent the area in square feet that can be painted, then the total cost of painting the walls can be expressed as \( 3.5A \).

Since Mrs. Pete has a maximum budget of $350, the appropriate inequality would be:

\[ 3.5A \leq 350 \]

This represents that the total cost \( 3.5A \) must be less than or equal to her budget of $350.

Therefore, the correct model that can be used to find the largest area that can be repainted is:

3.5A ≤ 350
