Answer:
12 hours
Step-by-step explanation:
Step one:
given data
base fee= $60
charge per hour= $15
let the number of hours the plumber work be x
the linear function for the charge is the equation of line.
that is y=mx+c
Step two:
given that y=$240
240=15x+60
240-60=15x
180=15x
divide both sides by 15 we have
x=180/15
x=12
<u>The number of hours is 12</u>
The answer is either 10:16 or 5:8
Given:
this year's population: 400 students
next year's population: 120% of this year's population
this year's population x rate of next year's population = next year's population
400 students * 120% = 480 students CHOICE D.
There will be 480 students next year.
