The equation 25=1.5x+.5y can be used to represent their profit of $25,where x represents the number of cookies and y respresents the lemonade.what is the slope represented by this equation?

Equation: 25=1.5x + 0.5y represents the profit of $25

x represents number of cookies

y represents the lemonade

Solution:

Plot a graph of number of lemonades (in the y-axis) against number of cookies (in the x-axis)

The equation of the straight line should be:

0.5y = -1.5x + 25

Divide through by 0.5 to get;

y = -3x + 50

The slope is -3 which means that three lemonades are used to produce one cookie.

8.1822x10^8

or 818,220,000
