Answer:
$5.75x5=$28.75
$28.75-$4.50=$24.25
Step-by-step explanation:
A tip is an additional payment which is voluntary contributed to the waiter to credit his efforts or service. In this case,the tip is 15%. from the original cost of $247.62, the total cost sam has to pay is $247.62 * 1.15 equal to $284. 763. it is expected to have a larger payment.
Because when you buy something and there is a sales tax it adds the choosen percentage to the price. So like if there is a Bike for $75 and the Goverment wants 8% of the $75 the store would charge $6 more because 8% of $75 is $6 and the sales tax would be that $6
For the first is 3864
The second is 1320
A=3.14(which is pie) x 20.5^2
A=420x pie
A=1320
For the third is 2544
3864-1320=2544
Sorry if this is wrong too.
