b) 1200
c) 300
d) 1000

Answer 1

To find the total number of houses in the neighborhood, set up a proportion using the given information. Solve the proportion to find the total number of houses. Hence the correct answer is option B

Step-by-step explanation:

To find the total number of houses in the neighborhood, we can set up a proportion based on the given information.

We know that 5% of the houses have red mailboxes, which is equivalent to 60 red mailboxes. Let's represent the total number of houses as x.

The proportion will be: (5/100) = 60/x.

Cross multiplying, we get: 5x = 100 * 60.

Dividing both sides by 5, we find that x = 100 * 60 / 5 = 1200.

Therefore, the total number of houses in the neighborhood is 1200.

Hence the correct answer is option B
