If Bob purchases both hamburgers and shakes, what is the maximum number of hamburgers he can purchase? A 7 B 8 C 9 D 10 E 11 Trail and Error method is perfect one for this question. we need to maximize the number of Hamburgers. Total = 56.. price / hamburgers = 5 and price / shakes = 4. 5x + 4y = 56. For value 11, 10, 9 of x , y won't be integers. 5*11 = 55 5*10 = 50 5* 9 = 45 5*8 = 40. we start with 11 as we want to maximize the number of hamburgers. So , we need to spend max balance on hamburgers. 5*8 + 4y = 56 4y = 16 y = 4. integer value. Thus , max hamburgers will be 8. B is the correct answer.

so
5*8+4*4 = 56
IMO B

Case 2
spend< 56$then 5*10 +4*1 = 54 IMO D max burgers D 10 Bob can spend a maximum of$56 on hamburgers and shakes. Hamburgers co   [#permalink] 21 Jan 2019, 08:43
