A decade ago, the average class size at Belmont Middle School was 30 students. Now it is
40% larger. What is the average class size currently?
PLS HELP

Answer 1

First let's find larged amount

`\\ \sf\longmapsto 40\%\:of\:30`

`\\ \sf\longmapsto 0.4(30)`

`\\ \sf\longmapsto 12`

Class size=30+12=42students

Answer 2

• 42 students

Explanation:

Initial class size = 30 students

Class size now is 40% larger:

• 30 + 40% =
• 30 + 30*40/100 =
• 30 + 12 =
• 42
