Question

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 1

we make an expression

`12* x=17`

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

`x=(17)/(12)=1.42`

multiply by 100 to obtain a percentage

`1.42*100=142`

the percentage is 142%
