Question

Mindys dog, Rex weighed 80 pounds a year ago. Now he weighs 92 pounds. What is the percent increase in his weight

Answer 1

15%

Explanation:

Initial Weight = 80 pounds

Final Weight = 92 pounds

Increase Percent =
`(Value Increased * 100)/(Initial Value)`

=
`((92-80)*100)/(80)`

=
`(12*100)/(80)`. (cutting the zeroes)

=
`(12*10)/(8)` (dividing by 4 in the denominator and numerator)

=
`(3*10)/(2)`. (dividing by 2 in the denominator and numerator)

=
`(3*5)/(1)`

= 15%
