Answer:
1200 ml per hour
Step-by-step explanation:
To compute what rate is 300 ml over 15 mins as a rate of ml per hour, we do a rule of 3, using a variable x as that amount of ml we don't know yet. We should have everything in the same units, so instead of writing 1 hour we write 60 minutes:
Now we solve for x:
And so, now that we know the value of x, the rate we wanted to find is
Which is just 1200 ml per hour.
Total number of units= 3+1
=4
4u=72
1u= 72/4
=18
Cheeseburger= 18x3
=54
Hamburger= 18

Step-by-step explanation:
This problem expects us to model the equation for the total cost of the services of the plumber given the conditions stated.
Say the fixed amount charged for coming to your house is $10
say the fix amount charged per is $3
and the time spent to do the job is X
Hence the scenario can be modeled as
the equation is similar to the equation of a straight line
