Excellent 

Wait I did it wrong

Let X be the no of boys

No of girls = 0.95X

Also as per question

X = 4 + 0.95X

0.05X = 4

X= 80

No of girls= 0.95 X = 76

Total members in club = 80+76 = 156
 

Bold=Correct 

Excellent 

Let's say cayden had x dollar. So Jayden had (784-x) dollar from 1st information.

From 2nd information:

x-x/6=(784-x)-124,

or, x*11/6=660

or, x=360.

So, cayden had 360$ at first.

Question answered here

1/5*1/4=1/5    1/5+1/5=2/5    1-2/5=3/5     3/5----)233-77=156

1/5----) 156÷3=52      5/5---)52*5=260

0.05 * 4 = 0.20

1.00 - 0.20 = 0.80

80 members in the club

x/3 = x/4 + 18

-x/4     -x/4

(x/3 - x/4) = 18

*multiply to change the denominators*

(4x/6 - 3x/6) = 18

x/6 = 18

6(x/6) = 6(18)

x = 108

Now we just halve that to get the number

108 ÷ 1/2 = 54

54 is the answer

Set the number of friend is x, the number of marbles is y.

everyone 11 marbles, left 6 marbles

So      11x + 6 = y     (1)

everyone  14 marbles, red 12 marbles

So      14x - 12 = y     (2)

according to (1), (2)

     11x + 6 = y      =>     x = 6

     
     14x - 12 = y              y = 72

So there are 6 friends, 72 marbles.

63 is the answer

Thanks

answer is there

assumed all r tuna

(15×$2.40-$35.10)÷($2.40-$2.30) = 9

7 books

$27

3x + 6= 5x - 8

3x - 5x = -14

-2x= -14

x= 7 books

he has (3×7)+6= $27
