Answer:
they make $19 dollars in profit per sweater
Step-by-step explanation
154/11 is 14. This means that they paid $14 dollars per sweater.
363/11 is 33, meaning that they sold each sweater for $33.
$33 - $14 is $19, thus they made $19 dollars per sweater.

Answer: There were 115 cats at the pet store.
Step-by-step explanation:
Hi, to answer this question we have to use proportions:
Since the number of cats to dogs at the pet store was 5 to 8.
The proportion is cats / dogs = 5/8
For 184 dogs = x / 184
Where x is the number of cats:
5/8 = x/184
Solving for x:
5/8 (184) =x
115 =x
There were 115 cats at the pet store.

Answer:
she use 750 mL of 0.22% solution and 250 mL of 0.1%
Step-by-step explanation:
given data
salt water solution 1 = 0.1%
salt water solution 2 = 0.22%
1 liter of solution contains salt = 0.13%
solution
we will consider here quantity in liters of the 0.22% solution is = x
so that the quantity of 0.01% solution will be = 1 - x
so amount of salt in the mix will be as here
0.22 % (x) + 0.1 ( 1-x) = 0.13% (1)
solve it we get
x = 0.25
and
1-x will be = ( 1 - 0.25 ) = 0.75
so she use 750 mL of 0.22% solution and 250 mL of 0.1%
