Answer:
Velma's share = 26.7%
Winnie's share = 33.3%
Zoe's share = 40%
Step-by-step explanation:
Let Velma's share be <em>v</em>.
Let Winnie's share be <em>w</em>.
Let Zoe's share be <em>z</em>.
Velma pays 25% more of Winnie's share
<em>v</em> = <em>w</em> + 25% of <em>w</em> = 125% of <em>w</em> = 1.25<em>w</em>
<em />
Zoe pays 50% more of Winnie's share
<em>v</em> = <em>w</em> + 50% of <em>w</em> = 150% of <em>w</em> = 1.5<em>w</em>
<em />
Total rent = <em>w</em> + 1.25<em>w </em>+ 1.5<em>w </em>= 3.75<em>w</em>
<em />
Velma's share =
Winnie's share =
Zoe's share =
a) The function that represent this situation is y = 90 + 8x.
b) His weight be after 8 weeks is 154 lbs.
<u>Step-by-step explanation:</u>
It is given that,
- He started at 90 kilograms.
- And gained weight at a constant rate of 8 lbs a week.
a) Write a function to represent this situation. Use x and y as your variables.
- Let 'x' be the number of weeks he gained weight.
- Let 'y' be the total weight.
Hence the equation can be framed as,
Total weight = starting weight + weight gained in x weeks.
We know that, each week he gains 8 lbs. Therefore, for 8 weeks he gained 8x lbs of weight.
⇒ y = 90 + 8x.
∴ The function that represent this situation is y = 90 + 8x.
b) What would his weight be after 8 weeks?
To find his week after 8 weeks, substitute x=8 in the function y = 90 + 8x.
⇒ 90 + 8(8)
⇒ 90 + 64
⇒ 154 lbs.
∴ His weight be after 8 weeks is 154 lbs.
