If Monica's heart beat is 225 times in 3 minutes. 225 ÷ 3 = 75 beats per minute.

Jordy's heart beat 360 times in 5 minutes. 360 ÷ 5 =  72 beats per minute.

So your answer is B. Monica had the faster heart rate of 75 beats per minute.

Hope this helps. :)

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
