A bill for dinner was 28.85. Estimate the 15% tip for that dinner.
A $8.00
B $5.00
C $3.00
D $6.00
whoever helps me can you give a a mini explanation.. please!?
First, we must convert the 15% to an actual number that can be used in a calculation. For a percent, this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.
Second, you need to find out what 15% of your $28.85 meal cost is. This is always done by multiplying 0.15 by $28.85 and getting 4.3275. We need to round this number because you cant leave $4.3275 as a tip! When it is rounded, we get $5.00. So it is B. $5.00.
yay! thank u mr bobbie!!!!!
Ms. Bobbie. (And I'm actually a student too)
To estimate the 15% tip for the dinner bill, you can follow these steps:
1. Calculate 10% of the dinner bill amount by moving the decimal point one place to the left (this is equivalent to dividing by 10).
For example:
- 28.85 / 10 = 2.885
2. To calculate the 15% tip, you can take half of the 10% value calculated in step 1 and add it to the 10% value.
For example:
- (2.885 / 2) + 2.885 = 4.3275
Rounded to the nearest dollar, the estimated 15% tip for the dinner bill is $4.00.
Therefore, among the given choices:
- Option A ($8.00) is too high
- Option B ($5.00) is too high
- Option C ($3.00) is lower than the rounded up tip amount
- Option D ($6.00) is too high
So, the correct answer would be C. $3.00
