After having a lot of fun with her friends in the carnival photo booth, Isabelle decided to set up a photo booth at her birthday party.She bought an instant camera and tripod for 115.60 Then, she bought some photo props. Isabelle spent a total of 138.98 on the supplies for the photo booth. Let p represent the cost of the photo props. Which equation models the problem? 115.60+p=138.98 p-115.60=138.98 Solve this equation to find the cost of the photo props.

To model the problem, we need to set up an equation that represents the total cost of the photo that Isabelle spent a total of $138.98 on the supplies, and she bought an instant camera and tripod for $115.60. Let $p$ represent the cost of the photo props. The equation that models the problem is:<br /><br />\[ 115.60 + p = 138.98 \]<br /><br />Now, let's solve this equation to find the cost of the photo props.<br /><br />Step 1: Subtract $115.60 from both sides of the equation to isolate $p$.<br /><br />\[ p = 138.98 - 115.60 \]<br /><br />Step 2: Perform the subtraction.<br /><br />\[ p = 23.38 \]<br /><br />Therefore, the cost of the photo props is $\$23.38$.
