title: Laravel calculate in blade
body: <p>i have some problems with calculating some prices that i need on my page.
  I have variable <code>$days</code>, and price like this </p>
  
  <p><code>$price = _amount($change-&gt;price, $change-&gt;currency, get_display_currency());</code>. </p>
  
  <p>Now that price is clear for example 13.50, but it's price for 1 day, variable <code>$days</code> give's me value that i have to multiply with <code>$price</code> and give's me correct price for example 40.5$ (if it's value of $days = 3).
  If i want to echo $price i need to write $price['value'] to get 13.50, but that's not problem.
  Can anyone tell me how to multiple this price with days?</p>
