Answer:
-3
Step-by-step explanation:
To find the slope given two points
m = (y2-y1)/(x2-x1)
= (-5-7)/(-4- -8)
= (-12)/(-4+8)
=-12/4
= -3
The balance in dollars at the end of 4 years will be $1,462.50
His basic salary is $ 2,500, his commission on sales is 3% (on sales only)
At the end of te month he got $3,040
Let x be the TOTAL sales performed during this month, so the money generated from sales (only) is (x).(3%), Hence the equation:
2500 + (x).(3%) = 3040
2500 + x(0.03) = 3040
x(0.03) = 3040-2500
x(0.03) = 540
and x = 540/0.03
x = $18,000
Amount spent on the last call = $25 - $22.04 = $2.96 = 296 cents
Number of minutes used for last call = 296 / 8 = 37 minutes.
