Problem 1:

A toy car is on sale for 40% off. If the original price was $40, what is the new sales price?

Solution:
1. Calculate the discount amount:
\[
\text{Discount} = 40\% \times 40 = 0.40 \times 40 = 16
\]
2. Subtract the discount from the original price to find the new sales price:
\[
\text{New Sales Price} = 40 - 16 = 24
\]

Answer:
\[
\boxed{24}
\]

Problem 2:

I want to buy a book that is on sale with a 50% discount. If the sales price is $25, what was the original price?

Solution:
1. Let the original price be \( x \).
2. A 50% discount means the sales price is 50% of the original price:
\[
\text{Sales Price} = 50\% \times x = 0.50 \times x
\]
3. We know the sales price is $25:
\[
0.50 \times x = 25
\]
4. Solve for \( x \):
\[
x = \frac{25}{0.50} = 50
\]

Answer:
\[
\boxed{50}
\]

Problem 3:

After serious negotiating, you got a $25 discount on a pair of sneakers. If the original price of the sneakers was $125, what percentage discount did you get?

Solution:
1. The discount amount is $25.
2. The original price is $125.
3. Calculate the percentage discount:
\[
\text{Percentage Discount} = \left( \frac{\text{Discount Amount}}{\text{Original Price}} \right) \times 100 = \left( \frac{25}{125} \right) \times 100
\]
4. Simplify the fraction:
\[
\frac{25}{125} = 0.20
\]
5. Convert to a percentage:
\[
0.20 \times 100 = 20\%
\]

Answer:
\[
\boxed{20}
\]

Problem 4:

If you buy 2 pens you get a 50% discount on the second pen. If 1 pen costs $2.30, how much will 2 pens cost you?

Solution:
1. The cost of the first pen is $2.30.
2. The second pen has a 50% discount:
\[
\text{Discounted Price of Second Pen} = 50\% \times 2.30 = 0.50 \times 2.30 = 1.15
\]
3. Add the cost of the first pen and the discounted second pen:
\[
\text{Total Cost} = 2.30 + 1.15 = 3.45
\]

Answer:
\[
\boxed{3.45}
\]

Problem 5:

I got a $12 dollar discount on a $60 head set. What was the percentage discount I got?

Solution:
1. The discount amount is $12.
2. The original price is $60.
3. Calculate the percentage discount:
\[
\text{Percentage Discount} = \left( \frac{\text{Discount Amount}}{\text{Original Price}} \right) \times 100 = \left( \frac{12}{60} \right) \times 100
\]
4. Simplify the fraction:
\[
\frac{12}{60} = 0.20
\]
5. Convert to a percentage:
\[
0.20 \times 100 = 20\%
\]

Answer:
\[
\boxed{20}
\]

Problem 6:

I got a 12% discount on a pair of jeans and a 25% discount on a t-shirt. If the original price of the jeans was $100 and that of the t-shirt $50, how much did I pay for both items?

Solution:
1. Calculate the discount on the jeans:
\[
\text{Discount on Jeans} = 12\% \times 100 = 0.12 \times 100 = 12
\]
\[
\text{Price after Discount} = 100 - 12 = 88
\]

2. Calculate the discount on the t-shirt:
\[
\text{Discount on T-Shirt} = 25\% \times 50 = 0.25 \times 50 = 12.50
\]
\[
\text{Price after Discount} = 50 - 12.50 = 37.50
\]

3. Add the discounted prices of both items:
\[
\text{Total Cost} = 88 + 37.50 = 125.50
\]

Answer:
\[
\boxed{125.50}
\]
