From the amounts that are given, the ratio of the earnings will be 3:2:1.
<h3>How to calculate ratio</h3>
From the information, the eldest earns R270, the middle child earns R180 and the youngest earns R90.
Therefore, the common factor to the numbers will be 90. Therefore, the ratio will be:
270/90 = 3
180/90 = 2
90/90 = 1
The ratio is 3:2:1.

Answer:
26
Step-by-step explanation:
Since x = -5, we can replace x with it's numerical -5, right? The problem tells you that x is equal to -5. So, just replace any x you see with -5.
So in this case,

turns into:

You can use a calculator or solve it by hand to see what the answer is.

Slope-intercept form is as shown here: y = mx + b
(-8, 1) and (0, -5) in slope-intercept form will be y = -3/4x - 5
(-3, -8) and (2, 7) in slope-intercept form will be y = 3x + 1
We use x to represent the price of the cheapest hat. Since the more expensive hat is twice the price of the cheaper one, we use 2x to represent it. Therefore x + 2x, or 3x, equals $75.12. Divide 75.12 by 3 to find x, which is 25.04. The more expensive hat is 2x, so we must multiply 25.04 by 2 to find the price of the more expensive hat. Therefore, the cost is $50.08.
