The numbers going to the left on a number line means the values are smaller and the numbers going to the right means the values are bigger.

Take the value '0' for example, the value on the right of zero is '1', which is a value bigger than zero, and the value to the left of '0' is '-1', which is a value smaller than zero.

Apparently, the calculator at the link in your lesson is fully capable of giving you the necessary numbers. My own TI-84 work-alike gives me the account balances, but the rest of the numbers need to be figured.

In 30 years, there are 12×30 = 360 months, or 4×30 = 120 quarters. See the calculator results below. Your table can be filled in using the given information to find the contribution amount. The calculator gives the final balance. The interest amount is found by subtracting the contribution amount from the final balance.

$\begin{array}{cccc}\text{Opt}&\text{Contributions}&\text{Int}&\text{Final Bal}\\1&360\cdot 25=9000&6250.50&15250.50\\2&120\cdot 75=9000&8467.04&17467.04\\3&1000&5489.17&6489.17\end{array}$

Answer:

$we \: have \: 5x + 6x + y + y + 3y + 4 + 6 + 2 \\ x \: terms = 5x + 6x = 11x \\ y \: terms = y + y + 3y = 5y \\ constant = 4 + 6 + 2 = 12 \\ then \: 11x + 5y + 12 \\ option \: (c) \\ thank \: you$
