Alvin opened a savings account. at the end of the first year, his savings account had $22,000. at the end of the second year, his savings had $19,000, and at the end of the third year, his savings had $16,000. using the pattern, predict how much money alvin will have in his savings account at the end of the fifth year. $10,000 $19,000 $13,000 $14,000

As we can see from the question, the pattern that emerges is that each year since the end of the second year, Alvin's account is being reduced by $3,000.

So, at the end of the third year his account is $19000-$3000=$16000

Likewise, at the end of the fourth year his account will have $16000-$3000=$13000

Thus at the end of the fifth year his account will have $13000-$3000=$10000

Therefore, from the given options, $10000 is the correct answer.

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
