Pls help me get a good grade

Step-by-step explanation:

To find the unit rate, divide the numerator and denominator of the given rate by the denominator of the given rate.

On call: 3.5 hours is $10

We are trying to find the cost per hour, which means 3.5 needs to become a one. Therefore the amount of hours is the denominator:

Unit rate is $2.90 for an hour: $10/3.5 = 2.2.85714285714/1 = 2.86/1

Talk time: (3/4 is .75 hours) .75 hours is 1.75

You would multiply 0.06 by 60 because syou are going from a smaller unit (which is minuetes) to a bigger unit (which is hours)

0.06*60= 3.60

On call: $2.86 per hour

Talk time: $2.30 per hour

Another company: $3.60 per hour

The cost per hour is $3.60, which more than the other two costs, therefore it is not a better deal.
