Answer:
250 boys
Step-by-step explanation:
We know that the ratio is 9:10 from girls to boys
Take 225 and divide it by 9
225 ÷ 9 = 25
So we know that 25 is a factor of 225
We can the number of boys and multiply it by 25 to get 250
If we put it in the ratio form:
225:250 = 9/10
Check work:
25 x 9 = 225
25 x 10 = 250
12 - x = 5
Subtract 12 from both sides
12 - 12 - x = 5 - 12
- x = - 7
Divide both sides by -1
-x/-1 = -12/-1
x = 7
To find out how many did not raise money, we need to find the percentage that did not raise money and multiply that by the total number of members.
If 95% raised money, 5% did not raise money.
0.05 x 80 = 4 members did not raise money
