Answer:
375 + 320
Step-by-step explanation:
375 adult
320 students
equals 395
1. We know that 30% expressed as a decimal is 0.30
Since 30% of people were using the internet, 0.30*3200 is our answer.
3200*0.30= 960.
Therefore 960 people were using the internet out of the 3200 surveyed.
Amy can estimate with 10% instead, so she can just simply move the decimal point of $9.11 to the right, and so it will be estimated to more than 91 cents.
