Answer:
$27.5
Step-by-step explanation:
12.5 x 2.20 = 27.5
Multiply 48,000 by 2.3 to get 110,400
She needs to sell $110,400 products next month
Percent formula : is / of = % / 100
12 is ? % of 200..
is = 12
of = 200
% = x
now sub and solve
12/200 = x / 100
cross multiply because this is a proportion
(200)(x) = (12)(100)
200x = 1200
x = 1200/200
x = 6.......so 12 is 6% of 200 <==
Step-by-step explanation:

In each proof, start by looking at what you're trying to prove. We want to prove that two triangles are congruent. To do that we use one of the following: SSS, SAS, ASA, or AAS.
To decide which one to use, look at the information given. We're given two pairs of congruent sides, so we can narrow the strategy down to either SSS or SAS. We aren't told anything about the third pair of sides, but we <em>can</em> see that ∠JNK and ∠MNL are vertical angles. We'll use this to show the triangles are congruent by SAS.
1. JN ≅ MN, Given
2. ∠JNK ≅ ∠MNL, Vertical angles
3. NK ≅ NL, Given
4. ΔJNK ≅ ΔMNL, SAS

Repeat the same steps as 20. Again, we're trying to prove two triangles are congruent, so we have 4 strategies to choose from. Just like before, we're given two pairs of congruent sides, so we'll use either SSS or SAS. And again, we aren't told anything about the third pair of sides, but we can see that both triangles are right triangles. So we'll use SAS again.
1. MN ≅ PQ, Given
2. ∠LMN ≅ ∠NQP, Right angles are congruent
3. LM ≅ NQ, Given
4. ΔNML ≅ ΔPQN, SAS
