Answer:
You use the quadartic foruala for this problem your fanial anwers is
x=1 + or - radical 37 / 6.
1+ radical 37 over 6 =1.180460422
To the nearest tenth =1.2
1-radical 37 over 6= -0.8471270884
To the nearest tenth=-0.8
x² + 3x - 10 = 0
x = -(3) ± √((3)² - 4(1)(-10))
2(1)
x = -3 ± √(9 + 40)
2
x = -3 ± √(49)
2
x = -3 ± 7
2
x = -3 + 7 U x = -3 - 7
2 2
x = 4 U x = -10
2 2
x = 2 U x = -5
Solution Set: {2, -5}
J not here because
Brand C does not have a lower unit cost than brand B
Brands D does not have a higher cost than brand A
And brand A and C don’t have the same cost
