Step-by-step explanation:
Y = Ax2 Bx C
Enter coefficients here >>> 4 7 -20
Standard Form: y = 4x²+7x-20
1.75 0.875 0.765625 3.0625 -23.0625
Grouped Form: No valid Grouping
Graphing Form: y = 4(x+0.88)²-23.06
Factored Form: PRIME
Solution/X-Intercepts: -3.28 AND 1.53
Discriminate =369 is positive, two real solutions
VERTEX: (-0.88,-23.06) Directrix: Y=-23.13
Given :
Insurance cost , $693.00 .
Gas cost , $452.00 .
Average charge per fare , $7.00 .
Tuition fee , $3280.00 .
To Find :
The fare he have to get to pay his fee .
Solution :
Let , number of fair required is n .
Therefore , total profit is :
Now , to pay his fee this profit must be equal to his fee because he don't have other expenditure .
So ,
But number of rides cannot be in decimal so minimum rides he must get is
632+1 = 633 .
Hence, this is the required solution .
