Answer:
5.72
Step-by-step explanation:
(-16.75 + 16.75) = 0
0 + 5.72= 5.72
Therefore, the answer is 5.72
Answer:
The linear function is: p(x) = 3x+65The linear function is: p(x) = 3x+65
Step-by-step explanation:
Let x be the number of t-shirts and y be the total pay
As we can clearly see in the table that there is a linear relationship between x and y
A linear function is given as:
Here m is the gradient of the function then
Taking any two pairs of x and y
(1,68) and (2,71)
Putting in equation
Putting a pair (1,68) in the equation to find the value of b
Putting the value of b
Let p(x) be the linear function
Hence,
The linear function is: p(x) = 3x+65
(a) 3x=4(x-2.25) (or simplified: 3x=4x-9)
(b) 3x=4x-9
0=x-9
x=$9
(c) 3x9=27
4x9=36
36-9=27
and 27=27 therefore they spent the same and it is correct
(d) Tanya's items cost $9 each and Tony's items cost $2.25 less than this, or $6.75
4,900 x 0.0725 =355.25
So,
775+355.25= $1 130.30
So she made $1 130.30!
