Answer:
what number and what variable
Step-by-step explanation:
Answer:
131.25
Step-by-step explanation:
25r²-10r+10r-4=0
25r²-4=0 (Since -10 and 10 cancel each other out)
25r²=4
Divide both sides by 4 to get r² = 6.25
Square both sides to get r = 2.5
Plug 2.5 back into the equation to get the answer of 131.25
Answer:
Step-by-step explanation:
Answer:
P = $ 482.00
Equation:
P = I / rt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
P = 72.3 / ( 0.05 × 3 ) = 482
P = $ 482.00
The principal required to
accumulate interest of $ 72.30
on a rate of 5% per year for 3 years is $ 482.00.
hope it helps :)
