-39/4 decimal form is -9.75 mixed number form is -9 3/4
Step-by-step explanation:
On call = 3.5 hours for 10 dollars => ½ hour for 1.25 dollars. Now, let’s solve the unit rate for each company first = 3.5 hour / 10 dollars => 10 / 3.5 => Unit rate is 2.9 dollars/hr Second company = ½ hour for 1.25 dollars => 1.25 / .5 => 0.25 dollars / hr. Thus, the first company pays better than the second one because it pays 2.9 dollars every hour of talk compare to the 2nd one which pays only 0.25 dollars per hr.
