Answer:
A.
[tex]\dfrac{x}{195}=\dfrac{100}{130}[/tex]
B. 150
Step-by-step explanation:
Let x be the number of people at the club last year.
The attendance of your club increased by 30% from last year. This means that if the last year attendance was 100%, this year attandance is 100% + 30% = 130%
Thus,
x people - 100%
195 people - 130%
A. Write a proportion:
[tex]\dfrac{x}{195}=\dfrac{100}{130}[/tex]
B. Cross multiply:
[tex]130\cdot x=100\cdot 195\\ \\130x=19,500\\ \\13x=1,950\\ \\x=\dfrac{1,950}{13}=150[/tex]
