He had 5 more nickels then he originally thought...so he had 25 cents more then he thought he had......so if he had 4.35......he thought he had 4.35 - 0.25 = 4.10......which is 4.10 / 0.05 = 82 nickels

or this way....
4.35 / 0.05 = 87 nickels....what he had
and if he had 5 more nickels then he thought he had...then he thought he had 87 - 5 = 82 nickels

If each years cumulate an increase of 1100 dollars, then the cost after 22 years will be the base cost (27000) plus 22 increases (22*1100), for a total of

$27000 + 22\cdot 1100 = 27000 + 24200 = 51200$

This relates to arithmetic series as follows: a series is arithmetic if, given a starting element $x_0$ , every next element is given by adding a fixed number, called common difference, $r$ . So, the first terms are

$a_0 = x_0$
$a_1 = x_0 + r$
$a_2 = x_1 + r = (x_0+r) + r = x_0 + 2r$
$a_3 = x_2 + r = (x_0+2r) + r = x_0 + 3r$
$a_4 = x_3 + r = (x_0+3r) + r = x_0 + 4r$

So, you can see that the element $x_n$ is obtained by adding n times the common ratio to the starting element.

Since the element $a_n$ represents the cost after n years, we are interested in the element

$a_{22} = x_0 + 22r = 27000 + 22\cdot 1100 = 512000$

As we had already calculated.

Each set of ordered pairs represents a function. Write a rule that represents the function (0, 0), (1, 1), (2, 4), (3, 9), (4, 1

gulaghasi [49]

The function rule is y=x^2.

You can find y by multiplying x by itself twice. For instance, 4^2=4 x 4=16.

Hope this helps✨❤️
