Question
Figure 9.3.1 : I’m confused with the solution for question with figure 9.3.1 is:
15 x 10 + 5 × 10 = 175
But how come there is 5 x 10? I know that this is because 20 - 15 = 5, but where does "20" come from? Is it because the “Quantity” is 60, therefore 60 - 40? = 20? thats why 20 - 15 = 5? I’m confused where 20 comes from.
Figure: 8.4.2:
I know that the answer is “B”, but can someone please show me the calculation that I need to get this answer as this sort of questions will come up on my exam and I need to know these calculations to solve these types of questions.
