the first yr a community college offered a Certificate in data management , 12 people earned the certificate. the next year 17 people earned the certificate. what was the percent increase in the # of people earning the certificate?



Answer :

we make an expression

[tex]12\times x=17[/tex]

we know that if we multiply to twelve by the ratio of increase we will obtain 17

now solve for x that is the ratio

[tex]x=\frac{17}{12}=1.42[/tex]

multiply by 100 to obtain a percentage

[tex]1.42\times100=142[/tex]

the percentage is 142%
