Answer: after 2 monthly price reductions
Step-by-step explanation:
Given that :
Wholesale cost = $20 each
Markup = 50%
Selling price = $20 + (50% * 20) = $30
After each month selling price reduces by 20%;
Dip in price per month for which item didn't sell ;
Let m = Number of months
$30 - 0.2(30)m = $30 - 6m
After how many monthly price reductions did the price dip below the wholesale cost?
$30 - 6m < $20
-6m < $20 - $30
-6m < - $10
m > 10/6
m > 1.667
m = 2
After 2 monthly price reduction
1800 cm: 20 m in its simplest form is 9cm : 10 cm
<h3>What is ratio?</h3>
Ratio says how much of one thing there is compared to another thing. Ratio compares value.
Therefore, let's make the unit the same.
0.01 m = 1 cm
20m =
length = 20 / 0.01
length = 2000 cm
Therefore, the ratio is as follows:
1800 cm : 2000 cm
Let's write it in it simplest form.
1800 / 2000 = 9 / 10
Therefore, the simplest form is 9 cm : 10 cm

Step-by-step explanation:
Answer:
A unit rate describes how many units of the first type of quantity corresponds to one unit of the second type of quantity.
So, six bottles by 678 pennies:
6*678=6*(600+70+8)=3600+420+48=4020+48=4068
so she has 4068 pennies
