Answer:
$144
Step-by-step explanation:
Let the money which Siti has be x
Therefore, the money June has will be x+240
First condition is that June gave 25% of her money to Siti, So this amount will be deducted from June's money and will be added in Siti's money.
Siti's money = x+ [25%(x+240)] June's money = x+240-[25%(x+240)]
= 1.25x + 60 = 0.75x + 180
Second condition is that Siti now gave 20% of her money to June.This amount will be deducted form Siti's money and added in June's money.
Siti's money = 1.25x+60-[20%(1.25x+60)]
= x+48
June's money = 0.75x +180+[20%(1.25x+60)]
= x+192
Difference between Sitit and June's money = x+192-x-48
= 144
Hence, June has $144 more money than Siti.

Answer:
825 g
Step-by-step explanation:
Here's my work:
500g Cl2 l 1mol Cl2 l 2 mol NaCl l 58.5 g NaCl
l 71 g Cl2 l 1 mol Cl2 l 1 mol NaCl
= 823.94 - the rounding can be a little off
The first thing you have to do is convert the 500 g of Cl2 into moles. So you get the mass of Cl which is 35.5, but Cl is diatomic by itself so you multiply 35.5 x 2 and get 71. now on the third column you are comparing the mol ratios of the equation. The equation is 2Na + Cl2 ---> 2NaCl, so you see that there is no coefficient in front of Cl2 so that means there is 1 mol, and then you see that in the product there is a coefficient of 2 in front of NaCl so that means there is 2 moles. Then finally you have to convert the moles backs into grams where you just add the masses of Na and Cl . You multiply across the top and then divide that number by the bottom row.
Answer: $0.98
Step-by-step explanation:
1/2 dozen is equal to 6 cupcakes
Divide 5.88 by 6 to get 0.98
This is the price for 1 cupcake, which is also the unit price.
