Aproduct costs $30.00 for 10 pounds. how much does it cost per ounce?

$30.00 / 10 pounds = $3.00 per pound.

1 pound = 16 ounces.

$3.00 / 16 ounces = $0.1875 per ounce.

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
