Answer:
The number of shirts to be purchased for price to be same is 6 .
Step-by-step explanation:
Given as :
The price for cool shirt = $ 8
The shipping charge for cool shirt = $ 13
The price for Tees = $ 7.50
The shipping charge for Tees = $ 16
Now, Let The number of shirts = S
So , According to question
∵ price to be same for both companies
∴ $ 8 × S + $ 13 = $ 7.50 × S + $ 16
Or, $ 8 × S - $ 7.50 × S = $ 16 - $ 13
Or, 0.5 S = 3
∴ S =
I.e S = 6
Hence The number of shirts to be purchased for price to be same is 6 . Answer
Answer:
Option (2).
Step-by-step explanation:
From the figure attached,
Since there is a common difference in each successive term and previous term of y,
= -3
= -3
Therefore, this data represents a linear equation.
Now we choose two points from the table given.
Let the points are (0, -6) and (1, -9)
Slope of this line 'm' =
m = = -3
Y-intercept 'b' = -6
Equation of the line will be,
y = -3x - 6
Option (2) will be the answer.
