Answer:
198 additional houses.
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
