Answer:
a) To determine an equation for the revenue, y, when x packages of batteries are sold, we need to know the price of each package of batteries.
Since the price of a package of batteries is $5.00, the revenue, y, when x packages of batteries are sold is given by y = 5x, where x is the number of packages of batteries sold and y is the revenue in dollars.
b) To find the maximum daily revenue that Rahj can expect from battery sales, we need to find the value of x that maximizes y = 5x.
Given that for every increase of 10¢ in the price A of a package of batteries, sales decrease by 10 packages per day. And the store normally sells 700 packages of batteries per day, at $5.00 per package.
It means that the store will sell a maximum number of batteries when the price is at $5.00
And the maximum daily revenue will be $5 * 700 = $3500.
So the maximum daily revenue that Rahj can expect from battery sales is $3500. And the number of packages of batteries sold when the revenue is at a maximum is 700.
The equation is y = 5x, where x is the number of packages of batteries sold and y is the revenue in dollars.
The zeroes of the equation are the points at which the function crosses the x and y-axis.
The x-intercept is the point at which the function crosses the x-axis. It happens when y = 0. So the x-intercept of this equation is (0,0)
The y-intercept is the point at which the function crosses the y-axis. It happens when x = 0. So the y-intercept of this equation is (0,0)
