</span>Give the scientific notation of 8.7 billion.
8.7 billion = 8 700 000 000
Scientific notation is the process of multiplying the given number by 10 to the
power of n.
Since billion has 9 zeros that’s equals
to 10^9
=> 8.7 x 10^9
let’s try solving this
=> 8.7 x (10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10)
=> 8.7 x 1 000 000 000
=> 8 700 000 000
Thus, our scientific notation of 8.7 billion is 8.7 x 10^9</span>

Answer:
(a) $1.32 per pen.
Step-by-step explanation:
(a) The total amount, $31.68, distributed amongst 24 pens, equates to each pen costing a total of $(31.68/24) = $1.32 per pen.
(b) The total amount of money which Mia will have to spend on pens this yeah is $(1.45*30) = $43.5, which is $11.82 more than $31.68. Therefore, Mia will need to spend $11.82 more on pens this year.
