Answer:
d= -5
Step-by-step explanation:
The slope of a line is found by finding the ratio of change is y values to change is x values
The points on the line have coordinates at: (-1,7) (-3,d)
where ;
Applying the formula with values as;
The value of d = -5
The coordinates of the points (-1,7) (-3,-5)
so solve for "x", to see how much is the company paying for the purchase of 1 minute
now, they're plan to sell the minute for 8cents, how much is the profit?
that is, the difference from their cost of the cents to the planned selling price.
bear in mind, is 46,000,000 minutes, so whatever value you get for 1minute,
you need to multiply it for 46,000,000 to get the actual cost.
and the revenue from the sell of 8cents per minute, is of course, 8 * 46,000,000
profit = revenue - cost
