Something is wrong with the question. TakeGMAT team please check.
Now it’s fine.
something wrong….ans is 1.62
Yup… no answer choices match with the correct answer…
H + C = 3.59
H + F = 4.4
F – C = 0.81
F = 2C
1.62
Yeah. I think choice E should be 1.62 rather than .162
answer is 1.62
may b it askd fr coleslaw & den (D) vil fit in,
else itz gota b 1.62,
knock~knock , Take GMAT Team kindly…get over it !!
E
Answer is D = 0.81 cents
Hamburger – 2.78 + .81 (colesaw) = 3.59
Hamburger – 2.78 + (.81 * 2) (fries) = 4.40
Simple!
Sorry babu! I agreed with you at first but after thinking the problem through a few times I noticed your second hamburger equation only finds the difference between the two prices and not the fry price. You have to treat the fry equation separately.
F = 2C
C = 3.59 – H
H + 2C = 4.40
H = Hamburger
Find the cost of a hamburger, then find the cost of coleslaw, then find the cost of fries.
I will vote for option E) $1.62
