<em>b)Amount = </em>$695
c)They will loose $215.
<em />
Step-by-step explanation:
From the question you should understand that;
- The charge is $35 per lawn
- The rental cost for aerating machine is $215
- The funds raised is the amount gained after aeration work minus the cost of renting the machine.
The equation that relates the fund raised and number of lawns aerated during a day is;
Let number of lawns aerated that day be l
The cost to aerate one lawn per day is $35
Cost to rent the aeration machine is $215
a)The equation is ;
= $35l-$215
b)Money raised
number of lawns,l=26
Substitute in the equation
Amount=$35l-$215
=$(35×26)-$215
=$910-$215=$695
c)If the team were unable to aerate due to weather condition, they will incur a loss to to renting of the aeration machine.They will lose $215.This can be avoided by not renting the aeration machine when the weather conditions seems unfavorable for working.

Answer:
- not linear
- somewhere between 184 and 186 (maybe)
Step-by-step explanation:
As you show, the weight differences are different for the same week differences, so the table is not linear. A graph (attached) can also show you the table is not linear.
__
The highest rate of weight loss shown in the table is 7 lbs in 3 weeks, or 4 2/3 pounds in 2 weeks. The lowest rate of weight loss shown in the table is 5 lbs in 3 weeks, or 3 1/3 pounds in 2 weeks. Based on the rates shown in the table, we might expect the starting weight to be between 3 1/3 and 4 2/3 pounds more than the first table value:
Week 0 weight: between 184 1/3 and 185 2/3 lbs, estimated.
_____
A "line of best fit" for the data has a y-intercept of about 185 pounds, which is the midpoint between our two estimates above.
Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (2, - 8) ← 2 points on the line
m = =
= - 4
The line crosses the y- axis at (0, 0) ⇒ c = 0 , then
y = - 4x + c , that is
y = - 4x → A
