A question from my math class:
valina [46]

Answer:

A) $29.68

B) $5.60

Step-by-step explanation:

<u>Part A Explanation)</u>

To find the total cost including tax, you must multiply the total cost by .06 because .06 out of 1 is 6%. <em>Quick explanation on percentages.</em>

<u><em>DO NOT FORGET TO ADD THE TOTAL COST</em></u>

28.00 + (28.00 * .06) = 29.68

<u>Part B Explanation)</u>

This is asking only for the tip, not including the total cost. However, we need the total cost to calculate the tip.

28.00 * .20 = 5.6

<em>.20 out of 1 is 20%</em>

Veronica bought 2.1 pounds of turkey at the deli. The price of the turkey was 2.87 per pound. She also bought 4.8 pounds of ham.
Brrunno [24]

Answer:

Choose the correct answer from your choices.

Step-by-step explanation:

First, we find the price of the turkey by multiplying the weight of turkey by the price per pound.

2.1 pounds of turkey at the deli. The price of the turkey was 2.87 per pound.

2.1 lb * 2.87 $/lb = $6.03

Then, we find the price of the ham by multiplying the weight of ham by the price per pound.

She also bought 4.8 pounds of ham. The price of the ham was 2.11 per pound.

4.8 lb * 2.11 $/lb = $10.13

Now we add the two prices together.

$6.03 + $10.13 = $16.16

The total price was $16.16
