Given:

You bought [tex]\dfrac{3}{4}[/tex] pound of fudge for 6.75.

To find:

The equation and solve the equation to find the cost of the fudge per pound.

Solution:

Let x be the cost of the fudge per pound.

You bought [tex]\dfrac{3}{4}[/tex] pound of fudge for 6.75.

[tex]\dfrac{3}{4}x=6.75[/tex]

[tex]3x=6.75\times 4[/tex]

[tex]3x=27[/tex]

Divide both sides by 3.

[tex]x=\dfrac{27}{3}[/tex]

[tex]x=9[/tex]

Therefore, the required equation is [tex]\dfrac{3}{4}x=6.75[/tex] and the cost of the fudge is 9 per pound.
