Work Step by Step

The ticket cost for adults, 11.25, can be rounded up to 11.30, so the cent side ends in a 0. This was done only to the cent side of the ticket cost in order to make the estimation more accurate. .25 rounds up to .30 because of the rounding up rule with the number 5. The ticket cost for children, 6.50, does not have to be rounded because the cent side of the ticket cost ends in a zero. Therefore, 11.30x1=$11.30$ and 6.50x3=$19.50$. 11.30+19.50=$30.80$
