Lisa is making headbands using ribbons she would like to make 12 headbands each one requires 15.5 inches of ribbon she estimates that she will need to buy 160 inches of ribbon is her estimate reasonable explain your reasoning

No it is not reasonable because you need 186 inches of ribbon and 160 is not nearly enough

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

the answer will be b x² +x-1
