Let's solve the problems step by step.

Problem 1:
Question: A clothing shop is having a 40% off sale. How much would a shopper have to pay for a $20 sweater with a 40% discount?
####
Solution:
1.
Calculate the discount amount:
- The discount is 40% of the original price.
- Original price of the sweater = $20.
- Discount amount = \( 40\% \times 20 \).
- Convert 40% to a decimal: \( 40\% = 0.40 \).
- Discount amount = \( 0.40 \times 20 = 8 \).
2.
Calculate the final price after the discount:
- Final price = Original price - Discount amount.
- Final price = \( 20 - 8 = 12 \).
####
Answer:
The shopper would have to pay
$12.

Problem 2:
Question: There are 35 students in Mrs. Brown’s class. 20% of her students received a B on the test. How many students received a B?
####
Solution:
1.
Calculate the number of students who received a B:
- 20% of the total students received a B.
- Total number of students = 35.
- Number of students who received a B = \( 20\% \times 35 \).
- Convert 20% to a decimal: \( 20\% = 0.20 \).
- Number of students who received a B = \( 0.20 \times 35 = 7 \).
####
Answer:
The number of students who received a B is
7.
