Question

If 90 students were surveyed and 50 said they would buy a wristband, how many wristbands should Monty order for the school of 1800 students?

Answer 1

He should buy 1000 wristbands.

Since 50/90 students said they would buy a wristband, we can set up this proportion.

`(50)/(90)`
`(x)/(1800)`

multiply 50 * 1800 divided by 90 = 1000
