Joaquin has 3,500 dollars in his bank account. He spends 300 dollars on a new laptop and 1,200 on a new phone. How much money does Joaquin have left in his account?

2,000 (3,500-300=3,200. 3,200 - 1,200 = 2,000)

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
