Answer:
In pic below
Step-by-step explanation:
Answer:
Initial charge is $2.5
Hourly charge is $3.5/hr
Equation is y=3.5x+2.5
Step-by-step explanation:
Getting slope
Get fixed charge
Get equation
The slope can be found as follows. For 1 hour, charges is $6 so making time in x axis while money charged in y axis, the first coordinate is (1, 6) while for 4 hours with charge of $16.5 the coordinate will be (4, 16.5)
The slope will be given by dividing change in y axis to change in x axis. This will be (16.5-6)/(4-1)=3.5
To get the fixed charge
Using the equation y=mx+c where m is slope while c is fixed charge, x is time and y is total cost then for 1 hour
6=3.5(1)+c
C=6-3.5=2.5
Therefore, generally the equation will be y=3.5x+2.5
Initial charge is $2.5
Hourly charge is $3.5/hr
Equation is y=3.5x+2.5
What are u asking ? 30 minutes of 3 hrs the fraction would be 2/6 simplified would be 1/3 and the percentage would be 33.3 repeating percent
Answer:
$4,720
Step-by-step explanation:
$4,000 fridge
$120/1 year
120 * 6 = 720
720 / 1 = 720
$720 for 6 years
720 + 4,000 = 4,720
$4,720
