The formula is
I=prt
I interest earned?
P principle 1295
R interest rate 0.07
T time 180/365
I=1,295×0.07×(180÷365)
I=44.70
If the bases ar same, assume exponents are same
if
x^z=x^m
assume z=m
so
base is both 7 therefor
3x+5=1-x
solve
add x
4x+5=1
minus 5
4x=-4
divide 4
x=-1
$13 x 1.06 = $13.78
The CD costs $13.78 after the tax is added on.
Hope This Helps You!
Good Luck Studying :)
