Amodel for this data is n=1.45t +25.9 where t represents time in years, with t=10 corresponding to the year 2010. according to the model in what year will the number of pet owners exceed 67.95 million

In year 2029

Step-by-step explanation:

N=1.45t+25.9

67.95=1.45t+25.9

67.95-25.9=1.45t

t=(67.95-25.9)/1.45

t=29

so if t=10 correspond to the year 2010, t=29 correspond to the year 2029

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
