To find the possible widths \( w \) for the frame that Reese can construct, we start with the inequality representing the total length of framing, which includes the lengths of the frame sides: \[ 2w + 28.5 \leq 115 \] Now, let's solve the inequality for \( w \): 1. Subtract 28.5 from both sides: \( 2w \leq 115 - 28.5 \) \( 2w \leq 86.5 \) 2. Divide both sides by 2: \( w \leq 43.25 \) Thus, the inequality is \( 2w + 28.5 \leq 115 \) and the solution shows that the possible widths for the frame Reese can construct are \( w \leq 43.25 \) cm. Now, let’s get framing!
