A castle has 34 small rooms and 47 large rooms. Each room has 32 candles in it. Which is the best estimate for the number of candles in the castle?

2600 candles

Step-by-step explanation:

34 x 32 = 1088

47 x 32 = 1504

1088 + 1504 = 2592

2592 rounded is 2600

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
