Ending inventory had been overstated by $8,000 and that the 2019 beginning inventory was overstated by $5,000. Before the effect of these errors, 2019 pretax income had been computed as $100,000. What should be reported as the correct 2019 pretax income before taxes

step-by-step explanation:

just keep timing it by 4.

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

1. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
