over 4 kg allow 20 minutes per kg, plus 90 minutes
always leave the turkey to rest for 30 minutes before carving, to retain the moisture.

he plans to carve the turkey at 17: 15.

what time should he start cooking the turkey? :

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
