Hannah got a perfect score on 3 more spelling quizzes this quarter than last quarter . if she doubles the number of perfect quizzes she had this quarter , she will tie the school record. the record is 3 times the number of spelling quizzes hannah scores perfectly on last quarter.

First, underline the key numbers

n=Perfect Quizzes last quarter

x=School record

n+3

3•2=x

Now we solve that

3•2=6

Now we know, x=6

If the record (6) is 3 times the number of spelling quizzes Hannah scored perfectly last quarter (n), then we know we have to divide the record (6) by 3 to know how many perfect quizzes were from last quarter.

6/3=2 so, n=2

The number of perfectly scored quizzes from last quarter is 2.
