Delisile spends 30% of her income on rent and 50%of the remaining on food and travelling. she pays R2200,00 per month for educat
DIA [1.3K]

The total monthly income of Delisile including her spendings is R 1,520,000

<h3>How to find Delisile monthly income</h3>

Given:

  • x = Total monthly income

  • Amount spent on rent = 39% of x

= 0.30x

Amount remaining = x - 0.30x

= 0.70x

Amount spent on food and traveling = 50% of 0.70x

= 0.50 × 0.70x

= 0.35x

  • Amount spent on education = R 220,000

  • Amount left = R 312,000

Total = rent + food + education + amount left

x = 0.30x + 0.35x + 220,000 + 312,000

x = 0.65x + 532,000

x - 0.65x = 532,000

0.35x = 532,000

x = R 1,520,000

The Line graph shows the number of marks Stacey scorer in her homeworks.
weqwewe [10]

<u>Given</u>:

The line graph shows the number of marks Stacey scored in her homeworks.

We need to determine the Stacey's mean score.

<u>Mean score:</u>

The total number of marks is given by

(0\times 4)+(1 \times 5)+(2\times 3)+(3\times 4)+(4 \times 3)+(5 \times 1)

Simplifying, we get;

0+5+6+12+12+5=40

Thus, the total number of marks is 40.

Sum of the number of marks scored is given by

4+5+3+4+3+1=20

Thus, the sum of the marks scored is 20.

The mean is given by

Mean=\frac{40}{20}

Mean=2

Therefore, Stacey's mean score is 2 marks.
