The maximum revenue Carmelo can make is $17.25.

Step-by-step explanation:

Hockey cards, x, sell for $0.03 and baseball cards, y, sell for $0.05.

The number of hockey cards Carmelo sells is at least six times the number of baseball cards he sells. There are at most 525 cards to sell.

Set of equations are :

     .....(1)

   ......(2)

Substituting x=6y in the second equation.

=>

=>

y = 75

And we know x = 6y; so

x = 450

Total revenue =

=

= $17.25

Hence, the maximum revenue Carmelo can make is $17.25.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

answer: y=0 if that is what u r looking for
