For this case we can use the following rule of three:
$ 500 ---------> 100%
$ 400 ---------> x
Clearing x we have:
x = (400/500) * (100) = 80%
Therefore, the percentage of decrease in the rent is:
p = 100-x
p = 100-80
p = 80%
Answer:
a proportion can be used to calculate p is:
p = 100 - ((400/500) * (100))
The first one is 15 mornings
The answer is 45.
15% = 0.15, since you move the decimal 2 places
0.15 x 300 = 45.
Answer:
its either -7 or 7 but im not super confidant in that answer but thats what makes sense to me
It will end up with other integers.
