I=prt if p=$300 r = 4% t=12
The question is asking: what does I equal if I = (p)(r)(t), and p = $300, r = 4% or 0.04 and t = 12
I = (p)(r)(t)
I = ($300)(0.04)(12)
Multiply 300 x 0.04 x 12
I = $144
I=prt if p=$300 r = 4% t=12
The question is asking: what does I equal if I = (p)(r)(t), and p = $300, r = 4% or 0.04 and t = 12
I = (p)(r)(t)
I = ($300)(0.04)(12)
Multiply 300 x 0.04 x 12
I = $144
Remember to change the percentage to a decimal by moving the decimal point two places to the left
p =300
r = .04
t = 12
I = pre
I = 300 * .04 * 12
I = $144
the interest is 144 dollars
*If this yearly interest and you have 12 months, then you need to change the t to 1 year. This would produce only $12.
