Answer: <em>$6,400</em>
Step-by-step explanation:
<em>First, let's take the given numbers</em>
<em>Starts the account with $1600</em>
<em>Deposits $200 each week after opening it</em>
<em>25 weeks</em>
<em>We can't count the first week because it says "thereafter"</em>
<em>So we need to do 24x200</em>
<em>which is 4,800</em>
<em>Now we must add the original amount deposited and the amount of money added in 25 weeks</em>
<em>1,600+4,800</em>
<em>$6,400</em>

First you put that then multiply inside of that then you cross over percent than boom there's your awnser your welcome
For this case we have that, the cost of 5 dolls is $130. If we want to know the number of dolls that can be bought with $390 we make a rule of three:
5 dolls -----------> $130
x --------------------> $390
Where the variable "x" represents the number of dolls that can be purchased with $390.
Thus, you can buy 15 dolls.
Answer:
15 dolls
The wall can be built in 22 days by 6 workers in first 6 days and 9 workers in the rest of time.
<h3>How to use inverse proportionality to determine building time of a wall</h3>
In this question we must use the definition of <em>inverse</em> proportionality, in which the number of workers (), no unit, is inversely proportional to the <em>building</em> time (), in days.
According to the statement, 6 workers spent 6 days building a wall and there are 24 days left for completion, but 3 more workers entered to reduce building time, which can be represented by the following expression:
In this scenario, the wall can be built in 22 days.
