You can use Template Literals which allows embedded expressions:
function totalCost(obj,a){
var price = document.getElementById(`price${a}`).value;
}
OR: Using String Concatenation (if browser is yet to support Template Literals)
function totalCost(obj,a){
var price = document.getElementById('price' + a).value;
}

Template literals is an ES6 feature and are still not supported by all the browsers(IE11[caniuse.com/#feat=template-literals]). So always suggest them as an alternative syntax.
