Answer:
$60 in total
Step-by-step explanation:
You find the amount to give for the tip first:
An easy way of doing percent's is getting 10% of a number. 10% of $50.00 you simply move the decimal to the left one time.
You would end up with $5.00 being 10% of $50.00.
Since you want 20% of $50.00 you would just simply multiply $5.00 (10% of $50.00) by 2. (2 * 10% = 20%).
This gives you $10.00.
By knowing 20% of $50.00 is $10.00 you then want to find the grand total you would have to spend in all so you add $10 to the $50 bill giving you a total of $60.00.
