Label the amount of memory and the cost for these tick marks.Memory (gigabytes)Cost (dollars)Here is a table that represents thesituation. Find the cost of 1 gigabyte. Youcan use as many rows as you need.1283264321. Did you prefer the double number lineor the table for solving this problem?Why?16842 1

Answer 1

To answer this question, you'll need to project the values of the cost of every memory on the table:

The rule is to fill in the blanks using half of the number preceding the slot we want to fill, it's a matter of pattern recognition. Take note, the two tables are one splited due to insufficient spacing.

The cost of 1GB is $ 0.25. I prefer the doubling of the lower numbers to get the higher ones because the pattern is easy to spot and apply.
