Answer:
1159
Step-by-step explanation:
She wants to read 1000 pages per week for five weeks.
So in total she wants to read 1000 * 5 = 5000 pages.
The first three weeks she read 894 pages per week.
So during the first three weeks she read a total of 894 * 3 = 2682 pages.
We want to find how many pages she must read per week for the last two weeks to reach her goal.
Goal: 5000 pages
Pages read so far: 2682
Weeks remaining: 2
To find how many pages she must read for the last two weeks we simply subtract the number of pages she read during the first 3 weeks (2682 ) by her goal ( 5000 )
5000 - 2682 = 2318
So she must read 2318 pages during the last 2 weeks.
If we want to find the amount of pages she must read per week during the last 2 weeks to reach her goal, we simply divide the amount of pages she must read during the last few weeks to reach her goal ( 2318 ) by the number of remaining weeks ( 2 )
2318 / 2 = 1159
So for the last two weeks she must average 1159 pages per week.
Find common denominators ...12 then subtract
For 12 number of shirts would the cost be the same
<u>Solution:</u>
Given, Some students want to rider shirts with their school logo.
Let the number of shirts taken be "n"
One company charges $9.65 per shirt plus a setup fee of $43.
![\text { Then, total cost }=43+9.65 \times n](https://tex.z-dn.net/?f=%5Ctext%20%7B%20Then%2C%20total%20cost%20%7D%3D43%2B9.65%20%5Ctimes%20n)
⇒ Total cost = 9.65n + 43
Another company charges $8.40 per shirt plus a $58 setup fee.
![\text { Then, total cost }=58+8.40 \times n](https://tex.z-dn.net/?f=%5Ctext%20%7B%20Then%2C%20total%20cost%20%7D%3D58%2B8.40%20%5Ctimes%20n)
⇒ Total cost = 8.4n + 58
We have to find for what number of shirts would the cost be the same?
So, we have to equate both the total costs
![\begin{array}{l}{\rightarrow 9.65 n+43=8.4 n+58} \\\\ {\rightarrow 9.65 n-8.4 n=58-43} \\\\ {\rightarrow 1.25 n=15} \\\\ {\rightarrow n=12}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7B%5Crightarrow%209.65%20n%2B43%3D8.4%20n%2B58%7D%20%5C%5C%5C%5C%20%7B%5Crightarrow%209.65%20n-8.4%20n%3D58-43%7D%20%5C%5C%5C%5C%20%7B%5Crightarrow%201.25%20n%3D15%7D%20%5C%5C%5C%5C%20%7B%5Crightarrow%20n%3D12%7D%5Cend%7Barray%7D)
Hence, students has to take 12 shirts for the cost to be same
Either 200.855 or 210,000,00 depending on if the e represents 10
