Jaquan begins his kindergarten year being able to spell 10 words. He is going to learn to spell 2 new words every day. Write an inequality that can be used to determine how many days, d, it takes Jaquan to be able to spell at least 75 words. Use this inequality to determine the minimum number of whole days it will take for him to spell at least 75 words.
10 + 2x > 75
x>37.5 -----> x>38
It will take Jaquan at least 38 whole days!
