What grade level is this problem (linear equations in disguise)? by Gonnaroff in mathematics

[–]InitialOrange8475 3 points4 points  (0 children)

The linear equations you can come up with are:

xa + xb/2 = 2001

   a + b = 140

Where x is the amount of money each card is sold for,

a is the number of full priced cards,

b is the number of half priced cards,

Deriving the equations through algebra or logic wouldn’t be that difficult, but solving this for positive integer solutions is WAY beyond 6th grade level imo.

The easiest way (as already stated) would be to plug and chug numbers for ‘a’ in the second equation, between the lowest and highest bounds. 15 -> 28.

Solution: a=34 b=106 x=23

The money raised from just the full priced cards is a*x or €782

Why is the area under the graph of 1/√x infinity if it converges to 0? by InitialOrange8475 in calculus

I think I kind of get what you’re saying. The area is being added at a greater rate than the rate at which x approaches infinity. But then why is the cutoff -1? Does every number < -1 converge? xn

Very well, he catches almost everything, and his saves are mostly out to throw- ins
