Tracy's retirement party costs $25 ,plus an additional $1 for each guest she invites. What is the maximum number of guests there can be if Tracy can afford to spend a total of $37 on her retirement party?

12 guest

Step-by-step explanation:

It cost $25, plus an additional $1 per guest. She wants to spend $37 on everything.

Let work this out:

37-25=12

She can invite 12 guest and meet her budget of $37.

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
