Answer:

$5.38

Explanation:

What we know:

- The Christmas cards had an original cost that was marked down by 65%

- The final selling price afterwards was $3.50

Let [tex]x[/tex] be equal to the original cost of the Christmas cards.

If [tex]x[/tex] was marked down by 65% to get $3.50, we can write this equation:

[tex](65 percent)x=3.5[/tex]

To solve for x, we need to first convert 65% into a decimal. To do this, we divide by 100.

[tex]65/100=0.65[/tex]

Now, our final equation looks like this:

[tex]0.65x=3.5[/tex]

[tex]0.65x=3.5[/tex]

Divide both sides by 0.65 to isolate x

[tex]\frac{0.65x}{0.65} =\frac{3.5}{0.65}\\x=5.38[/tex]

Therefore, the original selling price of the cards was $5.38.

I hope this helps!
