for(Account acc : Trigger.New) {
	if(acc.Name = "Test1") {
		acc.TextField1__c = "Test1";
	} else if(acc.Name = "Test2") {
		acc.TextField1__c = "Test2";
	}
}

I have a RichTextField__c that contains text like below:

Dear FirstName,

Please see below for details:
Total: $1000  <--- I need to get the number "1000" and save it to another custom field. 
 

Thanks,
FirstName

Is there a way for me to get the total amount only "1000" and save it as the value of another custom field using a trigger?
