Question

the value of a company's stock changes by -$2.25 each day. After how many days will the value of the stock change by -$18?

Answer 1

8 days

Explanation:

Set up a fraction. Let "x" be the variable.

`(-2.25)/(1)=-(18)/(x)`

Step 1: Apply fraction cross multiply

`\left(-2.25\right)x=-1\cdot \:18`

Step 2: Simplify

`-2.25x=-18`

Step 3: Divide both sides by
`-2.25`

`(-2.25x)/(-2.25)=(-18)/(-2.25)`

Step 4: Simplify

`x=8`

Answer 2

8 days. -18÷-2.25= 8
