Custom Fields Pro : Remove $ symbol from output field

I have a site for a business. It is done in wordpress and uses advanced custom fields pro (plugin) to set prices for services. I didn't write the site!!! There is a custom field set that you enter a number and it shows '$ number' on the site. I need to change the number field to accept a text string. I figured that out. Problem is there is still a $ symbol that shows on the page (the control in acf for this isn't set. So I looked around. and found this string on a home.php page:

foreach ($singleservice as $row) {
                $info = $row['service_information'];
                $price = $row['service_price'];
                $price = '$'.$price;
                echo '<div class = "singleservice clearfix">
                    <div class = "text">'
                        .$info.
                    '</div><!--text-->
                    <div class = "price">'
                        .$price.
                    '</div><!--price-->
                </div><!--singleservice-->';

It has been awhile since I've done any coding and would have thought the coder set this in afc plugin. But can I just change the above line: $price = '$'.$price; >to> $price = $price; ? OR am I missing something with the plugin or something else. I don't want to break anything big!!! I appreciate the help and knowledge here, thank you.
