Need with first second and third question

1.)

22.5c + 200 ≥ 500

Step-by-step explanation:

The fixed amount earned by her in one week without detailing any car is '$200'.

The amount earned by her for every car she details is '$22.5'.

The number of cars she details is given to be 'c'.

The total amount earned by her in one week if she details 'c' cars in that week = (Fixed amount) + (Number of cars detailed) × (Amount earned for each car detail)

Total amount = $200 + c × $22.5

The minimum amount she has to earn in that week is '$500'.

Therefore, Total Amount ≥ $500

200 + 22.5c ≥ 500

Therefore the inequality which represents the condition in question is:

200 + 22.5c ≥ 500

3.)

47.5v + 35 ≤ 450

Step-by-step explanation:

The shipping charges which do not depend upon the number of volleyballs in it is '$35'.

The amount  of each volleyball is '$47.5'.

The number of volleyballs they buy as given in the question is 'v'.

The total cost of buying 'v' volleyballs = (Number of volleyballs) × (Cost of each volleyball) + (Fixed shipping charges)

Total money spend = v × $47.5 + $35

The amount earned by the department on jeans day or the maximum amount department can spend on buying volleyballs is '$450'.

Therefore, Total money spend ≤ $450

47.5v + 35 ≤ 450

Therefore the inequality which represents the condition in question is:

47.5v + 35 ≤ 450
