tickets for a concert cost $35 for balcony seats and $75 for floor seats. tickets at the same venue for a theatrical production cost $25 for balcony seats and $60 for floor seats. if tickets for all the seats are sold, the venue generates $27,750 in revenue for a concert and $21,750 for a theatrical production. which system of equations can be used to find the number of floor seats and balcony seats in the theater? (there's 2)

35b+75f=27750  

25b+60f=21750

I think this is correct

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
