The local baseball team won the national championship last year. At the start of the baseball season, shirts signed by the team members sold for $250.
However, three months into the season, the team had a losing record and the
shirts were only selling for $75.
a.
Write an equation to represent this situation. Assume that the price of
the shirts decreased by the same rate each month.
b.
What was the monthly multiplier and percent of decrease?

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
