Estimate.
1.) A 15% tip on a $37 bill
2.) a 19% tip on a $53 bill
3.) a 17% tip on a $23 bill
What are your estimates?
This is certainly a valuable skill for you to master.
that's all it says. there's nothing else there
To estimate the tip amount, you can use the following steps:
1.) Calculate 10% of the bill amount by moving the decimal point one place to the left. For example, 10% of $37 is $3.70.
2.) Find half of the 10% amount by dividing it by 2. In this case, half of $3.70 is $1.85.
3.) Add the 10% and the 5% amounts together to get the estimate. So, $3.70 + $1.85 = $5.55. Therefore, a 15% tip on a $37 bill would be approximately $5.55.
Using the same steps, we can find the estimates for the other two scenarios:
2.) For a 19% tip on a $53 bill:
10% of $53 is $5.30, and half of $5.30 is $2.65. Adding them together, we get $5.30 + $2.65 = $7.95. Therefore, a 19% tip on a $53 bill would be approximately $7.95.
3.) For a 17% tip on a $23 bill:
10% of $23 is $2.30, and half of $2.30 is $1.15. Adding them together, we get $2.30 + $1.15 = $3.45. Therefore, a 17% tip on a $23 bill would be approximately $3.45.
