To raise money, a school is sponsoring a magazine subscription drive. by visiting the 90 homes in the neighborhood, one student was able to sell $375 worth of subscriptions. at the rate, how many additional homes will the student have to visit in order to meet a $1200 goal?

Step-by-step explanation:

First you have to determine how much on average the student made at each house.  $375 ÷ 90 = 4.1666666667.    Next divide $1200 ÷ 4.16666667 = 287.99.   Rounded up to 288.   However, the question asks "how many additional houses"  so  you have subtract the 90 original houses from the new 288 =  198 additional houses.  

198 additional houses.

Step-by-step explanation:

The given is 90 homes, one student visit sold $375 worth of subscription.

First, it is to determine the average a students makes at one house.  

$375/90 = 4.16667

Now divide the goal with the amount made at each house.  

$1200/4.16667 = 287.99

Round it to 288

The question said ‘how many additional houses’, so you subtract 90 from the total number of houses.

288 - 90 = 198 additional houses
