Nina earns $15 for each yard she mows. She wants to buy a dress that is $109. How many yards will she need to mow to earn the money for the dress. Explain.

Shes will have to mow the lawn at least 7 times. 109 divded by 15 equals 7.2. So at least 7 times

So we can write this our as a mathamatical equation like so 15x=109 just divide both sides by 15 and theres your answer x=7.27 so she would have to mow the lawn 8 times in order to gain the money needed to buy that dress
