Alex spent 25% of his money on a sports drink. then he spent 25% of the remaining money on trail mix. He had $9 left. how much d
Illusion [34]
Alex spent 25% first, so he has now 75%. Then, he spent another 25% of that remaining money, so 25% of 75% is 56.25%. He has $9 left, which means $9 is 56.25% of the money he began with. 

Set up a proportion: 
9/x = 56.25/100    (9 dollars out of starting money equals to 56.25 per 100)
cross multiply 9 and 100, 56.25 and x
900=56.25x
Isolate the variable by dividing each side by 56.25

x=$16

damaskus [11]

Answer:

Vennetta

Length of Venetta's paper clip chain = 3 feets 5 inches

Length of Bill's paper clip chain = 39 inches

Converting both Venetta's paper clip chain length to inches only :

1 foot = 12 inches

3 feets = (12 * 3) = 36 inches

Hence,

Length of Venetta's paper clip chain in inches :

(36 + 5) inches = 41 inches

41 inches > 39 inches .

Hence, Venetta has the long clip chain.
