Answer:
50 pounds for $14.29 is the better option.
Step-by-step explanation:
$5.79÷20=$0.2895 per pound
$14.29÷50=$0.2858 per pound
$0.2895-$0.2858=$0.0037 saved per pound.
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 question is asking you to find the slope. Slope intercept form is writen:
y = mx + b (m being the slope and b being the y-intercept)
The slope would be 5 and the y-intercept would be 0.
So, your answer would be y = 5x also known as C. y = 5x
Hope I helped! :)
