Answer:

13

Step-by-step explanation:

Since Seth pays $0.50 for each check he writes, he would write (let x be how many checks Seth wrote) "x" checks for $6.50. That means;

1 = 0.50

x = 6.50

Now let us set up a fraction:

[tex]\frac{0.5}{1}=\frac{6.5}{x}[/tex]

Step 1: Cross multiply

[tex]0.5x=1\cdot \:6.5[/tex]

[tex]0.5x=6.5[/tex]

Step 2: Divide both sides by [tex]0.5[/tex]

[tex]\frac{0.5x}{0.5}=\frac{6.5}{0.5}[/tex]

Simplify

[tex]x=13[/tex]

Therefore, Seth will write 13 checks for $6.50
