Daru is paid $120 for 7.5 hours of work. what is her rate of pay per hour?

$16

Step-by-step explanation:

To find this, divide the total amount paid, $120, by the number of hours, 7.5:

120÷7.5 = 16

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
