You want to find values of v (number of visors sold) and c (number of caps sold) that satisfy the equation
... 3v + 7c = 4480
In intercept form, this equation is
... v/(1493 1/3) + c/640 = 1 . . . . . divide by 4480
Among other things, this tells us one solution is
... (v, c) = (0, 640)
The least common multiple of 3 and 7 is 21, so decreasing the number of caps sold by some multiple of 3 and increasing the number of visors sold by that same multiple of 7 will result in another possible solution.
The largest multiple of 21 that is less than 4480 is 213. Another possible solution is (0 +213·7, 640 -213·3) = (1491, 1)
We can also pick some number in between, say using 100 as the multiple
... (0 +100·7, 640 -100·3) = (700, 340)
In summary, your three solutions could be
... (visors, caps) = (0, 640), (700, 340), (1491, 1)

Answer:
B 71/8
Step-by-step explanation:
2x² - 5x = -12
2x² - 5x + 12 = 0 (EQ 1)
expand 2(x - p)² + q = 0 ,
since (x - p)² = x² - 2xp + pq,
2x² - 4xp +2p² + q = 0 (EQ 2)
compare x⁰ (just a number, without x) in EQ 1 and EQ 2.
2p² + q = 12 (EQ 3)
compare x in EQ 1 and EQ 2,
-4p = -5
p = 5/4
Substitute p=5/4 into EQ 3,
2(5/4)² + q =12
q = 12 - 2(5/4)²
q= 71/8
