This is the concept of algebra. Let the price of envelope be $x ;
the price of notepad is $ 8x
the price of postcard is $ (x-0.02)
the total amount is $1.68
thus:
x+8x+(x-0.2)=1.68
10x-0.02=1.68
10x=1.68+0.02
10x=1.7
thus
x=0.17
hence the price of an envelope is x=$0.17= 17 cents
the price of notepad is 8x=0.17*8=$1.36
the price of a postcard is x-0.02=0.17-0.02=$0.15= 15 cents
I don’t get what you mean?
Year. Population
1995. 4,500
2000. 15% increase from 4,500
15% of 4500=0.15•4500=675
4500+675=
5,175
2005. 4% decrease from 5,175
4% of 5175=0.04•5175=207
5175-207=
4968
The first thing you should know is how long it takes each one to build a box.
We have then:
Frankie = 120minutes
Tisha = 120-40 = 80minutes
Then, we take the average:
(120 + 80) / (2) = (200) / (2) = 100 minutes.
answer
It takes them to build the speaker box 100 minutes.
