The answer to this questing is 100, because (23 x 2) + (18 x 3) = 100
Simplest way to do this:
number of books= 120
percentage represented by 120= 100%
increase current percent by 55%= 155%
: . 55% increase = original number of books * (155%)
= 120 * (155/100)
= 186
Answer:
Decrease of 4% ($4).
Step-by-step explanation:
Suppose the initial price was $100. An increase of 20% will make the price $120.
Now we decrease it 20% which brings it to 120 - 0.20 * 120
= 120 - 24
= $96.
So that's an overall decrease of $4 or 4%.
Answer:
$492.50
Step-by-step explanation:
To start off, we already know that Vanessa makes at least $400 every week. What we don't know is how much Vanessa makes from her 5% commission on what she sells.
To solve for that, we need to find what 5% of $1,850 is. This can be done by multiplying $1,850 by 5%. Remember, we need to change 5% into its decimal form (5% ->
-> 0.05).
$1,850 x 0.05 = $92.5
This means that Vanessa made $92.5 off of commissions last week. The last step is to add her base salary of $400 to her commission sales and we get our final answer.
$400 + $92.5 = $492.50
Vanessa's total pay last week was $492.50
