You would have to set the equation to the profit Jennifer got, which you know to be 63 dollars:
63=0.5e-5
To begin solving for e, which represents the number of erasers sold, add five to each side to get e alone.
68=0.5e
Multiply each side by two to get a whole x value on the right side
136=e
Jennifer sold 136 erasers
Answer:
Option A. (2, -22)
is the solution set for the equation given: y=-6x-10
Step-by-step explanation:
Solution set = (2, -22)
This means :
x = 2
y = -22
Prove:
So by putting the values of x and y in the given equation:
y=-6x-10
-22 = -6(2) - 10
By simplifying:
-22 = -12 -10
-22 = -22
(satisfied)
As the left hand side is equal to the right hand sand this means that the solution set is valid for given equation.
i hope it will help you!
