Answer:

17.5% of 360 =  63

Step-by-step explanation:

We are given a process of finding  17.5% of 120. Following the same process we have to determine the 17.5% of 360.

17.5% can be break down as 10% + 5% + 2.5%

Thus,

STEP 1 : Find  10% of 360 , we get,

\frac{10}{100} \times 360=36

STEP 2 : find  5% of 360, we get,

\frac{5}{100} \times 360=18

STEP 3: find 2.5% of 360 , we get,

\frac{2.5}{100} \times 360=9

STEP 4: 17.5% of 360 =  10% of 360 + 5% of 360 +  2.5% of 360

⇒ 17.5% of 360 =  36 + 18 + 9

⇒ 17.5% of 360 =  63

alexandr1967 [171]

The variable use to represent Goran's score is 4g = 60

<h3>How to use a variable to represent a score?</h3>

The product of 4 and Goran's score is 60.

Now let's use the variable g to represent the score of Goran.

A variable is an alphabet or term that represents an unknown number or unknown value or unknown quantity.

In simpler term a variable is a letter use to represent a number in an expression or equation.

Therefore, the expression can be represented as follows;

let

g = score

Hence,

4 × g = 60

4g = 60

divide both sides by 4

4g / 4 = 60 / 4

g = 15
