Question

a veterinarian in newberg treats a number of different kinds of animals every year.
pets treated by the vet
what percent of pets treated were dogs or birds?
write your answer using a percent sign (%)

Explanation:

Step1: Find the number of dogs, birds and total pets

From the bar - graph, the number of dogs \(d = 900\), the number of birds \(b=800\), and the number of other pets \(o = 800\).
The total number of pets \(T=d + b+o=900 + 800+800=2500\).
The number of dogs or birds \(n=d + b=900+800 = 1700\).

Step2: Calculate the percentage

The formula for percentage is \(P=\frac{n}{T}\times100\).
Substitute \(n = 1700\) and \(T = 2500\) into the formula: \(P=\frac{1700}{2500}\times100\).
\(\frac{1700}{2500}\times100=\frac{1700\times100}{2500}=\frac{170000}{2500}=68\).

Answer:

\(68\%\)
