I think it is a but I’m not sure
According to the statement,
(5/6)a - (1/3)a = 13
(5 - 2) a / 6 = 13
a = 26 gallons
6x^2 + 23x - 4 = 0
factorising:-
(6x - 1)(x + 4 ) = 0
x = 1/6 , - 4
Well, a liter is 3.78541 gallons so multiple that by 20, its 7<span>5.7082 round it, its 76. im not sure what it means by stocks because i dont have the question but hopefully the 76 helps</span>
Here
for number three 199.99×.15 = amount off
for number four 200,000×.05 = commission
