SOLUTION
Write out the given information
[tex]\begin{gathered} \text{Number of student=22} \\ \cos t\text{ the ticket=\$ 7.50} \end{gathered}[/tex]
For estimate
The number of the tudent will be estimated to
[tex]25[/tex]
The cost of the ticket will be estimated to
[tex]\text{ \$ 8.0}[/tex]
Hence
The estimated cost of the trip will be
[tex]25\times8=\text{ \$200}[/tex]
Therefore
Clarence is correct. 22 rounds to 25 and $7.5 rounds to $ 8. Then 25 x 8= $200
