Question

Of all seventh-grade students at hart middle school, 0.3% of the students own a pet iguana. If there are 610 seventh-grade students at hart, about how many own pet iguanas

Answer 1

About 2 students own a pet iguana

Explanation:

Step 1

Determine the expression for the total number of students that own pet iguanas as shown;

N=p×T

where;

N=total number of students that own pet iguanas

p=proportion of total students that own pet iguanas

T=total number of students

In our case;

N=unknown

p=0.3 % of students

T=610 students

replacing;

N=0.3% of 610

N=(0.3/100)×610

N=1.83, round up to 2 since 1.83 is closer to 2 than 1
