Challenge. a daughter is 28 years younger than her father. in 5 years, the father will be 3 times as old as his daughter. how old is each now?

Daughter is 9

Father is 37

Step-by-step explanation:

d= Daughter age

f= Father age

f =d+28

f+5=3(d+5) ---»» f= 3d+10

//put d+28 instead f// d + 28=3d + 10

2d = 18 --»» d=9

f = d+28 -»» f = 37

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
