Question

What is the maximum product of two positive numbers whose sum is 78?

Answer 1

sounds like a consecutive number thing

Answer 2

1520?

Answer 3

10+1 = 11; 10*1 = 10

6+5 = 11; 6*6 = 30

Answer 4

78/2 = 35+4 = 39 ... hmm

Answer 5

39^2 = 1521. 39-1 = 38, 78-38 = 40. 38*40 = 1520. My flawed reasoning anyway.

Answer 6

Assuming he doesn't mean two of the same number?

Answer 7

:) yeah, doesnt say the numbers cant be the same

Answer 8

maximum is 39^2 using calculus

Answer 9

1521

Answer 10

Yeah. I for some reason read "positive number" as "even number."

Answer 11

1521, using inequalities.
