Answer:
The term ‘per cent’ means ‘out of a hundred’. In mathematics, percentages are used like fractions and decimals, as ways to describe parts of a whole. When you are using percentages, the whole is considered to be made up of a hundred equal parts. The symbol % is used to show that a number is a percentage, and less commonly the abbreviation ‘pct’ may be used.

Two figures are said to be similar if they are the same shape. In more mathematical terms, two figures are similar if their corresponding angles are congruent , and the ratios of the lengths of their corresponding sides are equal.
<u>The following could be a correct first step to solving the equation 4(3+x)=36</u>
- 12 + 4 x = 36

Q1. The answer is 612.50
The function is C(p) = 175 + 3.5p
p - the number of pots
If we need to produce 125 pots, then p = 125
C(p) is then C(125). So calculate C(125)
C(125) = 175 + 3.5 * 125 = 175 + 437.5 = 612.5
So, the production of 125 pots costs $612.5.
Q2. The answer is 78.
The function is C(p) = 175 + 3.5p
C(p) is the cost of producing a p number of pots.
If our budget is $450, then C(p) = 450. So, we need to calculate p.
C(p) = 450
C(p) = 175 + 3.5p
450 = 175 + 3.5p
3.5p = 450 - 175
3.5p = 275
p = 275/3.5
p = 78.57
So, the number of pots that can be produced for $450 is 78.
We got 78.57 for p, but it must be rounded to the smallest rounded number because you cannot produce 0.57 of a pot.
