Determine the cost of parking for each given amount of time. 5 minutes costs $ 1 hour costs $ 1 hour and 50 minutes costs $ 2 hours costs $ 2 hours and 1 minute costs $ 3 and a half hours costs $ ( it is $3 per hour or fraction of an hour)

5 minutes costs $0.25;

1 hour costs $3;

1 hour and 50 minutes costs $5.5

2 hours costs $6;

2 hours and 1 minute costs $6.05;

3 and a half hours costs $10.5

Explanation:

Given the cost of parking for each hour is $3

Therefore, 1 hour = $3

By principle of unitary method;

a)1 hour (60 minutes) = $ 3

   5 minutes =

     = $0.25

b)1 hour (60 minutes) = $3

   1 hour 50 minutes = 60+50 minutes = 110 minutes =

    = $5.5

c)1 hour (60 minutes) = $3

  2 hours (120 minutes) =

   = $6

d) 1 hour (60 minutes) = $3

  2 hours 1 minutes = 120 + 1 = 121 minutes =

  = $6.05  

e) 1 hour (60 minutes) = $3

   3 and half hours = (3× 60) +30 = 210 minutes =

  = $10.5

Therefore, 5 minutes costs $0.25; 1 hour costs $3; 1 hour and 50 minutes costs $5.5; 2 hours costs $6; 2 hours and 1 minute costs $6.05; 3 and a half hours costs $10.5

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

part a: 1.08

part b: 27.59
