Step-by-step explanation:
<span>Product means, the answer of numbers being multiplied with
each other.
In the given situation, we need to find three numbers that will be multiplied
with each other to get a product which is 9000.</span>
<span>Now, let’s find the possible numbers to be multiplied:
=> 300 X 30 X 1
=> 9000 x 1
=> 9000
Or this one also applies:
=> 4500 x 2 x 1
=> 9000 x 1
=> 9000</span>
There are a lot of ways to get a product of 9000 by multiplying
3 digits.
A car dealership pays the sum of $8,350 for a car
The dealer mark up the car price by 17.4%
The retail price = Mark up percentage x original price of the car
Mark up = 17.4%
= 17.4 + 10
= 117.4%
Convert 117.4% to decimal
= 117.4/100
= 1.174
The retail price = $8, 350 x 1.174
= $9,802.90
The retail price of the car is $9,802.90
By rounding $24.97 to $25, she actually added 3 cents to the price of the shirt. After adding $25 + $13.75 and getting $38.75, she needs to subtract the 3 cents she added to find the exact sum which is $38.72.
Answer: A. Subtract $0.03
