c. Choose a value for d that is greater than $25 and less than $100. Calculate the

total cost of each of the possible presents for the value you chose. Then write a
short paragraph telling Winona and Takoda which present they should buy and
explaining why.

Let's choose d to be $50.

For the first present, the total cost would be $40 + d = $40 + $50 = $90.
For the second present, the total cost would be 2(d) = 2($50) = $100.
For the third present, the total cost would be $50 + 0.75d = $50 + 0.75($50) = $50 + $37.5 = $87.5.
For the fourth present, the total cost would be 3(d) = 3($50) = $150.

Based on the calculations, Winona and Takoda should buy the third present with the total cost of $87.5. This present offers the best value for money since it includes three times the number of books as the second option, for a slightly lower price. Additionally, compared to the first and fourth options, this present is more reasonably priced while still providing a good number of books for the money.

i want the number 36 thow

Let's choose d to be $36.

For the first present, the total cost would be $40 + d = $40 + $36 = $76.
For the second present, the total cost would be 2(d) = 2($36) = $72.
For the third present, the total cost would be $50 + 0.75d = $50 + 0.75($36) = $50 + $27 = $77.
For the fourth present, the total cost would be 3(d) = 3($36) = $108.

Based on the calculations, Winona and Takoda should buy the second present with the total cost of $72. This present offers the lowest cost among the options and still provides a good number of books. The first present is slightly more expensive, the third present is just slightly more expensive than the second but offers fewer books, and the fourth present is the most expensive option. Therefore, the second present provides the best balance of cost and number of books.

i mean 60

Let's choose d to be $60.

For the first present, the total cost would be $40 + d = $40 + $60 = $100.
For the second present, the total cost would be 2(d) = 2($60) = $120.
For the third present, the total cost would be $50 + 0.75d = $50 + 0.75($60) = $50 + $45 = $95.
For the fourth present, the total cost would be 3(d) = 3($60) = $180.

Based on the calculations, Winona and Takoda should buy the third present with the total cost of $95. This present offers the lowest cost among all options and includes a good number of books. The first present is more expensive, the second present is significantly more expensive, and the fourth present is the most expensive option. The third present provides a decent balance of cost and the number of books, making it the best choice for Winona and Takoda.

makeit easyer

Let's choose d to be $30.

For the first present, the total cost would be $40 + d = $40 + $30 = $70.
For the second present, the total cost would be 2(d) = 2($30) = $60.
For the third present, the total cost would be $50 + 0.75d = $50 + 0.75($30) = $50 + $22.5 = $72.5.
For the fourth present, the total cost would be 3(d) = 3($30) = $90.

Based on the calculations, Winona and Takoda should buy the second present with the total cost of $60. This present offers the lowest cost among all options and still provides a good number of books. The first present is slightly more expensive, the third present is just slightly more expensive than the second but offers fewer books, and the fourth present is the most expensive option. Therefore, the second present provides the best balance of cost and number of books.

make it clear

Let's choose d to be $60.

For the first present, the total cost is $40 + d = $40 + $60 = $100.
For the second present, the total cost is 2(d) = 2($60) = $120.
For the third present, the total cost is $50 + 0.75d = $50 + 0.75($60) = $50 + $45 = $95.
For the fourth present, the total cost is 3(d) = 3($60) = $180.

Based on the calculations, Winona and Takoda should buy the third present with a total cost of $95. This present offers the lowest cost among all options and includes a reasonable number of books. The first present is more expensive, the second present is significantly more expensive, and the fourth present is the most expensive option. Therefore, the third present provides the best combination of affordability and a good number of books, making it the ideal choice for Winona and Takoda.
