Answer:
4.638 × 10⁹
Step-by-step explanation:
Log 300 = a
Can be written an an exponential equation 10^a = 300
Total cup cake ordered = 8
Percentage 'P' of a quantity x can be calculated using:
p/100 * x
Here,
P = 50%
x = 8
Put these values in formula.
50/100 * 8
=> 1/2 * 8
=> 4
So, the 50% fewer cupcakes would be (8 - 4) = 4 cupcakes.
Answer:
Excluding the shipping fee -
23 - 4 = 19
For each book-
19/5
= $3.8
