Answer:
<em>The number of boys enrolled was 150. </em>
Step-by-step explanation:
Suppose, the number of boys enrolled was
As there were 200 more girls than boys, so the number of girls
Given that, the ratio of boys to girls was 3 : 7 , so the equation will be........
So, the number of boys enrolled was 150.
16.67% increase
finding the percentage price increase
we need to find the difference in percentage price between the 2 years
12%-10% = 2%
2%/12% x 100% = 100%/6 = 16.67%
20% increase between January 1st 2010 and January 1st 2011
Answer: 2 months, Total cost= $72
Let x denote the number of months then
For Club A fee= 28+22x
For Club B fee= 16+28x
Equating both we get
28 + 22x= 16+28x
28-16= 28-22x
12= 6x
x= 2
So after 2 months the fee will be same i.e. 28+22(2)= $72
the answer is 60
because 2(30)=60
