Identify which table shows a direct variation.
two tables. for each table the column headings are x and y. table 1 has column 1 values 3, 4.5, 7 and column 2 values 7.5, 11.25, 17.5. table 2 has column 1 values 1.5, 8, 13 and column 2 values 3, 12, 19.5.

a.
both tables

b.
table 1 only

c.
table 2 only

d.
neither table

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
