Oksi-84 [34.3K]

Answer:

896

Step-by-step explanation:

14 of 20 teens eats breakfast every morning.

The percentage of those who eat breakfast every morning

The reasonable prediction for the number of teens that eats breakfast every morning from 1280 teens will be 70% of 1280.

70/100 x 1280

0.7 x 1280

896

The prediction would be 896 out of 1280 teens eats breakfast every morning
