Answer:
The answer is 286 dollars.
Step-by-step explanation:
To find the 5% of a number is to multiply it by 0.05. 286x0.05 is 14.3

Answer:
Use the graphing calculator to graph the system of equations and find the solution where x is the total hats sold and y is the total t-shirts sold.
x + y = 152,
8.5x + 12y = 1,656
How many hats were sold?

Answer:
three basic methods of graphing linear functions.
The first is by plotting points and then drawing a line through the points.
The second is by using the y-intercept and slope.
The third is applying transformations to the identity function f(x)=x.
