Question 1

A food fair is going to be held at Zoo Lake. Chloe decides to set up a stall selling tortillas. It costs Chloe [tex]\( R5 \)[/tex] to make a tortilla and [tex]\( R500 \)[/tex] to rent the stall. She sells each tortilla for [tex]\( R15 \)[/tex].

The table below shows the income that Chloe will make if she sells the tortillas.

\begin{tabular}{|l|c|c|c|c|c|c|}
\hline
Number of tortillas & 0 & 50 & 100 & 150 & 200 & 250 \\
\hline
Total income ([tex]\( R \)[/tex]) & 0 & 750 & 1500 & 2250 & 3000 & 3750 \\
\hline
\end{tabular}



Answer :

Certainly! Let's go through the detailed step-by-step solution for calculating the income Chloe makes based on the number of tortillas she sells at the food fair.

### Step-by-Step Solution:

1. Understand the Scenario:
- Chloe rents a stall at Zoo Lake for R500.
- Each tortilla sells for R15.

2. Identify the Number of Tortillas Sold:
- The number of tortillas sold are given as: 0, 50, 100, 150, 200, and 250.

3. Calculate the Total Income:
- The total income for each number of tortillas is calculated by multiplying the number of tortillas sold by the income per tortilla (R15).

Let's break down the calculations for each case:

1. For 0 Tortillas Sold:
- Income = [tex]\( 0 \times R15 = R0 \)[/tex]
- Total income = R0

2. For 50 Tortillas Sold:
- Income = [tex]\( 50 \times R15 = R750 \)[/tex]
- Total income = R750

3. For 100 Tortillas Sold:
- Income = [tex]\( 100 \times R15 = R1500 \)[/tex]
- Total income = R1500

4. For 150 Tortillas Sold:
- Income = [tex]\( 150 \times R15 = R2250 \)[/tex]
- Total income = R2250

5. For 200 Tortillas Sold:
- Income = [tex]\( 200 \times R15 = R3000 \)[/tex]
- Total income = R3000

6. For 250 Tortillas Sold:
- Income = [tex]\( 250 \times R15 = R3750 \)[/tex]
- Total income = R3750

### Summary of Results:
The table below shows the income that Chloe will make if she sells the tortillas:

| Number of Tortillas | 0 | 50 | 100 | 150 | 200 | 250 |
|---------------------|-----|-----|-----|------|-----|------|
| Total Income (R) | 0 | 750 | 1500| 2250 | 3000| 3750 |

Each entry in the "Total Income" row is obtained by multiplying the number of tortillas sold by the income per tortilla (R15).

From this table, we can see that as Chloe sells more tortillas, the total income increases linearly.
