Answer:
The number of small mowers are 19 and the large mowers are 11.
Step-by-step explanation:
Given:
A garden supply store sells two types of lawn mowers. Total sales of mowers for the year were $8379.70. The total number of mowers sold the 30. The small mower cost $249.99 and the large mower costs $329.99.
Now, to find the number of each type of mower sold.
Let the number of small mower be
And the number of large mower be
So, total number of mowers are:
Now, the total sales of mowers are:
Substituting the value of from equation (1) we get:
<em>Subtracting both sides by 7499.7 we get:</em>
<em>Dividing both sides by 80 we get:</em>
The number of large mower = 11.
Now, to get the number of small mowers we substitute the value of in equation ( 1 ):
The number of small mower = 19.
Therefore, the number of small mowers are 19 and the large mowers are 11.
Answer:
slope = - 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 4, 7) and (x₂, y₂ ) = (0, 3) ← 2 ordered pairs from the table
m = =
= - 1
