ill give you a medal

Use the formula P = RB
Where P is the Percentage, R is the Rate in decimal and B is the base.
OpenStudy (anonymous):
i dont know how to do that my teacher didnt teach me
OpenStudy (ranga):
I will do the first one and you can get the idea how to do the rest.
P = RB
In problem 1)
B = 465
R = 0.24 (remember: 24% = 24/100 = 0.24)
P = RB = 465 x 0.24 = 111.60

so its kinda like 100% of 50 is 50?
OpenStudy (ranga):
yeah, something like that.
P = RB
For problem 2)
B = ?
R = 0.12
P = 103
Plug the numbers into the formula and solve for B
OpenStudy (anonymous):
thank you!!
OpenStudy (anonymous):
ok b is confuzing tho
OpenStudy (ranga):
P = RB
R = 0.12
P = 103
So
103 = 0.12 x B
To isolate B, divide both sides by 0.12
103 / 0.12 = B
B = 858.33

Do you want to try C?
OpenStudy (ranga):
They ask you to round to the nearest tenth, so the answer for B should be 858.3

C should be 14%
OpenStudy (anonymous):
all it gives me is 14.1
OpenStudy (ranga):
If that is the closest then I suppose you can use that. The actual answer comes to 13.99 which when rounded should be 14.0%.
The rest are all correct.
