Toni bought some jazz records at $4 each and some classical records at $6 each. If her purchases totaled $46,? find all possibilities for the number of each type of record that she bought.

1 jazz and 7 classical; 4 jazz and 5 classical; 7 jazz and 3 classical; 10 jazz and 1 classical

Step-by-step explanation:

Turn the problem into an equation with x representing the number of jazz records and y as the number of classcial records. The equation will look like this: 4x+6y=46

We can graph this equation

The possibilites are when both the x and y are positive and are whole numbers because you can't buy negative records and you can't buy fractions of records.

72 is the answer to this problem

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
