Answer:

logₐ(8) = 0.903

Step-by-step explanation:

logₐ(8) = logₐ(2)³

           = 3logₐ(2) [Since, \text{log}(x)^b=b\text{log}(x)]

           = 3(0.301) [Given → log(2) = 0.301]

           = 0.903

Therefore, logₐ(8) = 0.903 is the answer.

One pound of ground beef costs $3.99. Five pounds of ground beef costs $17.45. How much cheaper is the ground beef per pound if
xxTIMURxx [149]

Step-by-step explanation:

Ok, so, to find this, remember- to find the true price of an item, remember the equation (PRICE DIVIDED BY QUANTITY), this will give you true price. So, for the individual, its $3.99 for one pound. In bulk, to find the true price, do price divided by quantity. $17.45/5= 3.45. So thats the better deal. Anyways, to find out how much cheaper it is, subtract 3.45 from 3.99. The answer is .54, however, since you need to round to the nearest tenth place, the answer would be .50
