hope this help the 
68 rounded to the nearest tenth equals 70
and 76 rounded to the nearest tenth equals 80
so if you subtract 80-70=10 Tito increased the percent up to 10 dollars 

Answer:

the percent of increase is 11.8%

Step-by-step explanation:

Hello, I think I can help you with this

you can easily solve this by using a rule of three

if the prize tito paid is 100%, how many percent is $76?

if

$68.00 ⇒100%

$76.00 ⇒x%?

[tex]\frac{68}{100}=\frac{76}{x}[/tex]

isolating x

[tex]\frac{68}{100}=\frac{76}{x}\\ \\\frac{x*68}{100}=76\\\x=\frac{76*100}{68} \\\\x=\frac{7600}{68} \\x=111.76[/tex]

so, $76.00 is 111.76 % of $68

the percent of increase will be the difference

111.76%-100%=11.76%=11.8%

the percent of increase is 11.8%

I hope it helps , Have a great day
