If 20% of a school was made up of out-of-district students last year, but the number of out-of-district students increased by 50% this year, without any change in total enrollment, what percent of the students is out-of-district this year?

Respuesta :

Answer:

30% is enrolled out-of-district.

Step-by-step explanation:

According to the word problem, the number is increased by 50%.

To increase a number by a percent, multiply the number and the percent.

We can do this by changing both percents to decimals.

To change a percent to a decimal, divide it by 100.

[tex]20/100 = 0.2[/tex]

[tex]50/100=0.5[/tex]

The number is INCREASED by 50% so 0.5 would become 1.5.

[tex]0.2 * 1.5=0.3[/tex]

0.3 = 30%.
