Question

A 6th grade class wants to take a field trip to the aquarium. The teacher asks the students to estimate how much it will cost for 22 students to go to the aquarium if the tickets cost $7.50. Four students offer their estimates.

Answer 1

Write out the given information

`\begin{gathered} \text{Number of student=22} \\ \cos t\text{ the ticket=\$ 7.50} \end{gathered}`

For estimate

The number of the tudent will be estimated to

`25`

The cost of the ticket will be estimated to

`\text{ \$ 8.0}`

Hence

The estimated cost of the trip will be

`25*8=\text{ \$200}`

Therefore

Clarence is correct. 22 rounds to 25 and $7.5 rounds to $ 8. Then 25 x 8= $200
