\((100*0.05) + (100*0.04) + (150*0.03) = 5 + 4 + 4.5 = 13.50\) , Answer must be (E) 13.50

Notice that the question is using 100. This will simplify the arithmetic because you can slide decimal places

0.05 x 100 = 5 (shift decimal to right twice)
0.04 x 100 = 4
0.03 x 150 (remaining copies) = 4.5

Sum is 13.50

Advice: 3 x 150 is the same as 3(100+50)

Solution



Given
In this question, we are given that
    • A copy service charges $0.05 per copy for the first 100 copies, $0.04 per copy for the next 100 copies, and $0.03 per copy for all copies thereafter

To find
We need to determine
    • The service charge for 350 copies

Approach and Working out
We can deduce a generalised expression for n copies, where n > 200 (here 200 = 100 + 100)

Charge for the first 100 copies = 100 x 0.05 = 5
Charge for the next 100 copies = 100 x 0.04 = 4
    • Hence, charge for the first 200 copies = 5 + 4 = 9

For total n (>200) copies,
    • Total service charge = 9 + (n – 200) x 0.03

If n = 350, then the total service charge = 9 + (350 – 200) x 0.03 = 9 + 150 x 0.03 = 9 + 4.5 = 13.5

Thus, option E is the correct answer.

Correct Answer: Option E
