Answer:
Option A. 500
Step-by-step explanation:
From the question given, we obtained the following:
Numbers of home with pet dogs = 250
Percentage with pet dogs = 50%
Total number of homes =.?
Thus, we can obtain the total number of homes represented by the chart as follow:
Let T be the total number of Homes.
Number of homes with dog = percentage of homes with dog × total number
Numbers of home with pet dogs = 250
Percentage with pet dogs = 50%
Total number of homes = T
250 = 50% × T
Divide both side by 50%
T = 250 ÷ 50%
T = 250 ÷ 50/100
T = 250 × 100/50
T = 250 × 2
T = 500
Therefore, the total number of homes represented by the chart is 500.
