A = price of the desktop
b = price of the laptop
now, we know the laptop was more expensive than the desktop by 250 bucks, thus
b = a + 250.
for "a", he paid 8.5% in interest, for "b", he paid 5% in interest.
how much is 8.5% of a? well (8.5/100) * a, or
0.085a.
how much is 5% of b? well, (5/100) * b, or
0.05b.
now, we know the total charges for financing were $296, that means the interest paid in total was 296, thus whatever "a" or "b" are, we know that 0.085a + 0.05b = 296.

how much did the laptop cost? well, b = a + 250.
5 because these numbers are all equally divisible.
Fist plug in 7 in to the X values like so 12 (3 (7) +5 (7)) then solve in side the parenthesis 3×7 =21 and 5×7=35 then add them 35+21=56 and then you are left with 12(56) or 12×56= 672
Answer:
If you were to order them least to greatest, it would be:
4/8 < 9/16 < 4/6 < 3/4
If you were to order them greatest to least, it would be:
3/4 > 4/6 > 9/16 > 4/8
