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.

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

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

The answer is 225 miles per 4.5 hours. hope this ; )
