Question

Sarah and Michelle have 20 feet of shelf space in their dorm room. Sarah has tons of stuff and insists that she needs twice as much shelf space as michelle. If she gets her wish how much shelf space will Michelle be stuck with?

Answer 1

x = 6.67

Step-by-step explanation:

If we call

x = amount of shelf space Michelle gets

then we know that

the amount of shelf space Sarah wants = 2x

Now the the total shelf space is 20 ft; therefore, we must have

`x+2x=20`

which simplifies to give

`3x=20`
`\Rightarrow x=(20)/(3)`
`x=6.67`

Hence, the amount of space Michelle will be stuck with is 6.67 ft.
