my answers:
a.) 48.3 + 2mv
b.) 48.3 x 1.15= 55.545

a.) To calculate the total cost for Sheeyin and Kaitlyn's meals, you need to add up the individual costs for each item they ordered. Let's break it down:
Coffee: $3.50
Soup of the day: $5.95
Garden salad: $6.95
Catch of the day: We will represent it as "mv" (market value)
Cheesecake: $7.75
The simplified expression for the total cost would be: $3.50 + $5.95 + $6.95 + "mv" + $7.75. So, the correct expression would be 3.50 + 5.95 + 6.95 + mv + 7.75, or simply 24.15 + mv.
b.) To calculate a 15% tip on the total cost, you need to multiply the total cost by 0.15 (which is equivalent to 15%). The expression to calculate the tip on the total cost would be: 0.15 * (total cost expression). So, the correct expression would be 0.15 * (24.15 + mv).
c.) Now, let's assume the catch of the day costs $14.95. To calculate the total bill including the tip, you need to add the cost of the catch of the day to the total cost (without the tip), and then multiply the sum by 1.15 (to include the 15% tip). The correct expression for the total bill including the tip would be: 1.15 * (total cost expression + $14.95). So, the correct expression would be 1.15 * (24.15 + mv + $14.95), or simply 1.15 * (39.10 + mv).
Now, let's check your answers:
a.) Your answer 48.3 + 2mv is incorrect. It seems you have added the individual prices incorrectly. The correct total cost expression for their meals is 24.15 + mv.
b.) Your answer 48.3 * 1.15 = 55.545 is correct. Congratulations!
c.) Your answer 48.3 + 29.9 = 78.2 * 1.15 = 89.93 is incorrect. It seems you have calculated the total bill incorrectly. The correct expression for the total bill including the tip is 1.15 * (39.10 + mv). The correct calculation would be 1.15 * (39.10 + $14.95) = 1.15 * $54.05 = $62.16.
So, to summarize, your answer to b) is correct, but your answers to a) and c) are incorrect.
