Lucy was given 28.87 to buy 3 storybooks and 4 comic books. However she bought 4 storybooks and 3 comic books instead $2.69 left. How much did each comic book cost?

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.

hence, the inequality could be represented as:

250c+180g≥950

there is no grid
