Answer:
Step-by-step explanation:
First, add up the two numbers in the ratio to get 8. Next divide the total amount by 8, i.e. divide £40 by 8 to get £5. £5 is the amount of each 'unit' in the ratio.
To calculate the ratio of an amount we divide the amount by the total number of parts in the ratio and then multiply this answer by the original ratio. We want to work out $20 shared in the ratio of 1:3.

Answer:
3 dollars
Step-by-step explanation:
If a item is 10% off, it is worth 90% or 9/10 of it's actual worth. Knowing this and calling the original price x, we can make the equation 2.7 = 9/10x
Equation:
9/10 x =2.7
x = 2.7(10/9)
x= 3
Answer:
$324
Step-by-step explanation:
Two ways to look at it:
Change 25 % to a decimal
$400 x .25= $100 is the discount
$400- $100= $300
Sales Tax: change 8% to a decimal
300 x .08= $24
Total cost is $324
or you can say you are paying 75% for the camera since it is discounted 25%
So change 75% to .75
$400 x .75=$300
Sales Tax: change 8% to a decimal
300 x .08= $24
Total cost is $324
