Can you help me with proofs

Mathematics
1 answer:
Yuki888 [10]3 years ago
5 0
I got you :-) I love proofs, This one looked hard at first but ended up being a lot easier then I thought. It is easy to overthink these. Ok, so first, set up your proof statements to reasons etc. Write down the given information and there are only 2 additional steps. You must say that DA congruent to DA because they are the same side. Now, if you notice, your two triangles DAE and ABD have 2 sides that are congruent because they are given and the third side is the same. You now have SSS in which allows you to say that DAE is congruent to ABD.

If the cost of the materials for a basic bar of soap is $2.50 and Lyndi sells each bar of soap for $4.50, what is the markup per
Nadusha1986 [10]

Answer:

80%

Step-by-step explanation:

Cost of materials for a bar of soap = $ 2.50

Selling price for a bar of soap = $ 4.50

Markup percent = \frac{selling\ price\ per\ unit - cost\ per\ unit}{cost\ per\ unit} \times 100

Markup percent = \frac{4.50-2.50}{2.50} \times 100

= \frac{2}{2.50} \times 100

= \frac{200}{250} \times 100

= 20 \times 4

= 80<em>% </em>
