Caleb’s puppy weighs 2,250 grams. if the puppy weighed 600 grams at his last visit to the veterinarian’s office, what is the percent increase in the puppy’s weight rounded to the nearest whole number?

For this case we can make the following rule of three:
 2250 -----------> 100%
 600 -------------> x
 From here, we clear the value of x.
 We have then:
 
 Therefore, the decrease in percentage weight is:
 
 Round to the nearest whole number:
 x = 73%
 
 the percent decrease in the puppy's weight rounded to the nearest whole number is:
 x = 73%

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for

No he does not because he can only cover 12 square feet from 15 square feet which he will still need 3 more. this is because if 3×5=15 square feet and 15-12=3 which thats the answer
