Step-by-step explanation:
Answer:
b. $35.61
Step-by-step explanation:
First, convert the 25% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 25%) by 100%.So, the conversational term "25%" becomes 25% / 100% = 0.25 in terms of a real mathematical number.
Second, you need to find out what 25% of your $28.49 meal cost is.This is always done by multiplying 0.25 by $28.49, or
<h2> 0.25 x $28.49=$7.12.
</h2>
So, the amount of tip you are going to leave is $7.12.
This makes the total cost of your meal (to write on your charge slip or other payment)
<h2>
$28.49 + $7.12 = $35.61.
</h2>
A=pi*r^2=pi*12^2=452.39 cm^2
