Answer:
216 boys
Step-by-step explanation:
450 students: 20% girls, 80% boys
450*20%=90 girls
450*80%=360 boys
Students having mobile phones: 40% (OF THE 90) girls, 60% (OF THE 360) boys
90*40%=36 girls
360*60%=216 boys
[We honestly don't need to care about the girls without mobile phones as they are only asking how many boys have mobile phones]
20 hot dogs was eaten by the 10 people who attended the hot dog eating contest.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
