Answer:
cost of a box is $3.5
Step-by-step explanation:
given data
sold box = 18
earned = $136.50
solution
we consider here number of boxes of cookies is x
and
for we get Tyler sold cookies box so number of boxes we divide 702 cookies among 18 is
Tyler sold =
Tyler sold = 39 boxes
and
now we consider here y as cost of each box of cookies,
so for cost or sale price of the cookie boxes here we divided 136.50 dollars among 39 boxes
so
cost of each box =
cost of each box = 3.5
Thus, the cost of each box was 3.5
Answer:
We can predict the sales representative travelled 8 miles replacing x =8 and we got:
And we can predict the sales representative travelled 11 miles replacing x =11 and we got:
Step-by-step explanation:
For this case we have the following data:
Miles Traveled x: 2,3,10,7,8,15,3,1,11
Sales y :31,33,78,62,65,61,48,55,120
For this case we need to calculate the slope with the following formula:
Where:
So we can find the sums like this:
With these we can find the sums:
And the slope would be:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
We can predict the sales representative travelled 8 miles replacing x =8 and we got:
And we can predict the sales representative travelled 11 miles replacing x =11 and we got:
