Question

the graph below shows the pet ownership in a town of 1,650 households.

pets in household	percent
at least one dog	19.9
at least one cat	13
at least one dog and one cat	6.19

1. how many households have at least one dog?
2. how many households have at least one dog and one cat?

Explanation:

Step1: Convert percent to decimal

$19.9\% = 0.199$

Step2: Calculate dog-owning households

$0.199 \times 1650 = 328.35$

Step3: Convert percent to decimal

$6.19\% = 0.0619$

Step4: Calculate dual-pet households

$0.0619 \times 1650 = 102.135$

Answer:

1. 328.35 (or 328 when rounded to whole households)
2. 102.135 (or 102 when rounded to whole households)
