Nick decided to take 2/5 of the money in his bank account and donate it to a local charity. If nick donated 70$ to a local charity, what was the total amount in his bank account

175$

Step-by-step explanation:

70/2=35

35*5=175

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
