Answer:
Rafael gets $4,32 In tips. The old lady gets $41.68 in change.
Step-by-step explanation:
Step 1: To calculate the tip we must take into account that it is 8% of the total amount of the bill.
$54 * 8%/100% = $4,32
Rafael gets $4,32 In tips.
Step 2: Now we must calculate the change the old lady receives. For this, we must subtract from the $100 that she gives the part corresponding to the payment for food and the part corresponding to the tip.
$100 - $54 - $4,32 = $41,68
The old lady gets $41.68 in change.
Have a nice day!
