You can break the string with a comma in this case, and get the first index:

let texto = '24.95, <strong> Outro texto, </strong>';
let valor = texto.split(',');
console.log(valor[0]);

String with function name in JS How to stylize the "clean" icon of the input type search?

Do this on the client side (in js), you can simply do:

responseText = '24.95, <strong> Outro texto, </strong>'; // faz de conta
valorFrete = parseFloat(responseText)
alert(valorFrete);

In this way you already have the numerical value, ready for mathematical operations.

Note that this only works if you are sure that the first character will always be a digit.
