Question

What is the final amount if 893 is decreased by 19% followed by a further 17% decrease?
Give your answer rounded to 2 DP.​

Answer 1

Answer: 600.36

Step-by-step explanation:

First, we need to decrease 893 by 19%. To find 19% of 893, we can use an equation like so: x / 893 = 19 / 100. Then, we can cross multiply, so you get 100x = 16967. This can be simplified to x = 169.67. Now that we know 169.67 is 19% of 893, we can subtract 169.67 from 893 which gives us 723.33.

Next, we need to decrease 723.22 by 17%. Again, we can use an equation to solve it: x / 723.33 = 17 / 100. We can cross multiply to get an equation of 100x = 12296.61, which can be simplified to x = 122.9661. We can then subtract 122.9661 from 723.33 to get 600.3639. Then, we can round this down to 600.36 as a final result.
