I need help asap :):);)

first choice

Step-by-step explanation:

25+12.50h<_ 100

<_ means he can spend exactly 100 or less because that's all he has

Subtract 25 on both sides

12.50h<_ 100-25

12.50h<_ 75

Divide by 12.50

h<_ 6

2.9 years

Step-by-step explanation:

Female nurses function f(t)= 7300 + 25t

Male nurses function m(t) = 2500 (1.02)t = 2550t

In order to make the male nurses exceed female nurses we need to create the inequality like

Male nurses female nurses

2550t     7300 + 25t

2525t     7300

t  

t  2.891 ≈ 2.9 years

So in 2.9 years the No of Male nurses will exceed female nurses

Let check our answer

Female nurse after 2.9 years = 7300 + 25*2.9 = 7372.5

Male nurses after 2.9 years = 2550.2.9 = 7395

Clearly male nurses are more that female nurses after 2.9 years
