Travis, jessica and robin are collecting donations for the school band. travis wants to collect 20% more than jessica, and robin wants to collect 35% more than travis. if the students meet their goals and travis collects $43,how much money did they collect in all?
a $106.78
b $128.60
c $136.88
d $144.99

If you would like to know how much money did they collect in total, you can calculate this using the following steps:

Travis ... t = $43
Jessica ... j
Robin ... r

120% of j is t
120% * j = 43
120/100 * j = 43
j = 43 * 100 / 120
j = $35.83

r = 135% of t = 135% * 43 = 135/100 * 43 = $58.05

t + j + r = $43 + $35.83 + $58.05 = $136.88

The correct result would be C. $136.88.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
