You'll calculate the amount it was decreased by :
15% is also 15/100
15/100 * 42000
The two 0's in 100 cut 2 of the 0's in 42000 making it :
15/1 * 420
15* 420 = 6300
So, 6300 is the amount that the price is decreased by, but the question says the price of the PC (personal computer) after the decrease has happened not the price it decreased by :
So,
42000 - 6300 = 35700.
I’m pretty sure the answer is 160 because the rectangle on the top has a volume of 64(16 x 4) and the rectangle on the bottom has a volume of 96(2 x 4 x 12). Add those together and you get 160 cubed inches. Hope this helped :)
What is the question asking specifically? (:
Answer:
9 hours
Step-by-step explanation:
Firstly,
Minus $123.10 with $34
123.10-34
= 89.10
(bcuz $34 is the reservation fee)
Secondly,
Divide $89.10 with $9.90 to determine the hours
t = 89.10/9.90
= 9
Last answer = 9 hours
