Answer:
There are 32 dogs and 72 animals in total.
Step-by-step explanation:
In order to find the amount of dogs, you need to set up an equation to solve for the missing variable. Let 'c' be the amount of cats and 'd' be the amount of dogs. We know that there are 40 cats, so c = 40. We also know that there are 25% more cats than dogs, so we can form an equation to express this difference: 1.25d = c, indicating that the number of cats is equal to the total number of dogs, plus an additional 25%. Since we know c = 40, we can set our second equation equal to 40: 1.25d = 40. Using inverse operations, we divide both sides by 1.25 to get d = 32. So, d + c, or 32 + 40 = 72 total animals.
Salinas will use 32 gallons for 480 miles
<h3>How to calculate the number of gallons required ? </h3>
Salinas used 15.6 gallons of gas for 234 miles
Miles can be described as the distance travelled by an object or an individual
The first step is to calculate the number of miles travelled using 1 gallon
15.6= 234
1= x
cross multiply both sides
15.6x= 234
x= 234/15.6
x= 15
1 gallon will take her 15 miles
Therefore, the number of gallons required for 480 miles can be calculated as follows
1= 15
x= 480
cross multiply both sides
15x= 480
x= 480/15
x= 32
Hence Salinas will require 32 gallons for 480 miles of the journey
