UpStudy AI · Accepted Answer

1. Compute the following percentages:

a. Calculate $$30\%$$ of $$81.80$$:

- Express $$30\%$$ as a decimal: $$0.30$$.
   - Multiply: 
     $$
     0.30 \times 81.80 = 24.54
     $$
   - Answer: $$24.54$$

b. Calculate $$80\%$$ of $$R\,1.60$$:

- Express $$80\%$$ as a decimal: $$0.80$$.
   - Multiply:
     $$
     0.80 \times 1.60 = 1.28
     $$
   - Answer: $$R\,1.28$$

c. Calculate $$90\%$$ of $$R\,0.10$$:

- Express $$90\%$$ as a decimal: $$0.90$$.
   - Multiply:
     $$
     0.90 \times 0.10 = 0.09
     $$
   - Answer: $$R\,0.09$$

d. Calculate $$20\%$$ of $$R\,460$$:

- Express $$20\%$$ as a decimal: $$0.20$$.
   - Multiply:
     $$
     0.20 \times 460 = 92
     $$
   - Answer: $$R\,92$$

e. Calculate $$60\%$$ of $$R\,5.40$$:

- Express $$60\%$$ as a decimal: $$0.60$$.
   - Multiply:
     $$
     0.60 \times 5.40 = 3.24
     $$
   - Answer: $$R\,3.24$$

f. Calculate $$20\%$$ of $$86.40$$:

- Express $$20\%$$ as a decimal: $$0.20$$.
   - Multiply:
     $$
     0.20 \times 86.40 = 17.28
     $$
   - Answer: $$R\,17.28$$

2. Problem solving – Pair of Shoes with Discount

The problem states that a pair of shoes originally costs $$R\,150$$ and you received a $$25\%$$ discount.

- First, find the discount amount:
     $$
     25\% \text{ of } 150 = 0.25 \times 150 = 37.50
     $$
     
   - Then, subtract the discount from the original price:
     $$
     150 - 37.50 = 112.50
     $$
     
   - Answer: The final price is $$R\,112.50$$.
1. Calculate the following percentages: a. $$30\%$$ of $$81.80$$ is $$24.54$$. b. $$80\%$$ of $$R\,1.60$$ is $$R\,1.28$$. c. $$90\%$$ of $$R\,0.10$$ is $$R\,0.09$$. d. $$20\%$$ of $$R\,460$$ is $$R\,92$$. e. $$60\%$$ of $$R\,5.40$$ is $$R\,3.24$$. f. $$20\%$$ of $$86.40$$ is $$R\,17.28$$. 2. A pair of shoes originally costs $$R\,150$$ with a $$25\%$$ discount. After the discount, the final price is $$R\,112.50$$.
