A doll sold for $264 in 1977 and was sold again in 1985 for $433. Assume that the growth in the value of the collector's item was exponential. ...
a) Find the value k of the exponential growth rate. Assume V. = 264.

idk bring the function back   im not smart

step-by-step explanation:

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
