Keiko bough 3 pounds of fruit sale. How many ounces of fruit sale did keiko buy?

48 ounces

Step-by-step explanation:

1 pound = 16 ounces

3 lbs * 16oz = 48 oz

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
