The half gallon is better because you could buy 2 half gallons of milk and get the same amount for $2.98 which is less than $2.99
The solution is 2sqrt77/77. You just fill in 2/3 for the x's. When you do that, you do that you get (2/3)/sqrt(9-[2/3]^2) which, simplified, is (2/3)/sqrt(9-[4/9]). Now use the common denominator under the radical of 9 to get (2/3)/sqrt([81-4]\9). Simplifying even further gives you (2/3)/([sqrt(77)]/3). Now do that division by multiplying 2/3 by the reciprocal of ([sqrt(77)]/3) to get 2/sqrt77. I rationalized the denominator to get that result up there.
I’ll help if u attach the pic of the question:)
First, the mark down 15% would make the value 85% of the original, so doing 15.99*0.85 gives you 13.59. Then take that and multiply that by 0.5, because of the half price, to get a final price of $6.79
