What are the solutions to the following word problems? e) My mother bought 5 computer gadgets for R98 each. She bought 5 gadgets. How much did she pay altogether? f) I spent R600 on 6 computer games.

Here are the solutions to the word problems:

e) My mother bought 5 computer gadgets for R98 each. She bought 5 gadgets. How much did she pay altogether?
i. What is the question? How much did she pay altogether?
ii. What are the numbers? R98 and 5.
iii. What is the key word? "each" (tells me the price per item) and "altogether" (tells me to find the total, implying multiplication).
iv. What is the number sentence?

$$\text{R}98 \times 5 = \square$$

v. Solve it:

$$\text{R}98 \times 5 = \text{R}490$$

vi. Write a sentence: She paid R490 altogether.

f) I spent R600 on 6 computer games. How much did I pay for each game?
i. What is the question? How much did I pay for each game?
ii. What are the numbers? R600 and 6.
iii. What is the key word? "each" (tells me to divide).
iv. What is the number sentence?

$$\text{R}600 \div 6 = \square$$

v. Solve it:

$$\text{R}600 \div 6 = \text{R}100$$

vi. Write a sentence: I paid R100 for each game.

g) My mother went on a training course for 7 days. The lunch cost R75 per day. How much did she pay for her lunches?
i. What is the question? How much did she pay for her lunches?
ii. What are the numbers? 7 days and R75.
iii. What is the key word? "per day" (tells me the cost for one day) and "7 days" (tells me to find the total, implying multiplication).
iv. What is the number sentence?

$$\text{R}75 \times 7 = \square$$

v. Solve it:

$$\text{R}75 \times 7 = \text{R}525$$

vi. Write a sentence: She paid R525 for her lunches.

h) I have R400. Computer games cost R75 each. How many games could I buy?
i. What is the question? How many games could I buy?
ii. What are the numbers? R400 and R75.
iii. What is the key word? "each" (tells me the cost per item) and "how many" (tells me to divide to find the number of items).
iv. What is the number sentence?

$$\text{R}400 \div \text{R}75 = \square$$

v. Solve it:

$$400 \div 75 = 5 \text{ with a remainder of } 25$$

This means you can buy 5 games and have R25 left over.
vi. Write a sentence: I could buy 5 games.
