Final answer:
To calculate an 80% tip on a $44.98 bill, convert the tip to a decimal (0.80) and multiply by the bill amount, which gives $35.98 after rounding. Adding the tip to the original bill results in a total of $80.96 that should be left on the table.
Step-by-step explanation:
The subject of this question is clearly Mathematics, as it involves calculating percentages such as tax and tip which are common arithmetic operations. The question falls under the Middle School grade level category, as it involves basic concepts of percentages and simple multiplication. When Jennifer and her family plan to leave an 80% tip on their bill of $44.98, we first need to convert the tip percentage to a decimal by dividing by 100, which makes it 0.80.
Next, multiply the cost of the meal by the decimal tip rate:
0.80 × $44.98 = $35.984
Since we need to round to the nearest cent, the tip amount would be $35.98. Add this to the original bill to get the total amount:
$44.98 (original bill) + $35.98 (tip) = $80.96
Therefore, they should leave a total of $80.96 on the table to cover the bill and the 80% tip.
