Question

Keisha is reading a 350 page book at a rate of 27 pages per day. Use a point-slope equation to determine how many pages she will have left to read after reading the book for 10 days. She will still have ____ pages left yo read after 10 days.

Answer 1

The number of pages left to read after 10 days is 80 .

Explanation:

Given as :

Keisha reading 350 pages book at rate of 27 pages per day .

Let The x pages will be read in 10 days

Now ,

`(Page* Day)/(Work)` = constant

So.
`(P_1* D_1)/(W_1)` =
`(P_2* D_2)/(W_2)`

Or,
`(350* 1)/(27)` =
`(350* 10)/(x)`

Or, 350 × 1 × x = 350 × 10 × 27

So, x = 270

So, The page read on 10 days = 270

∴ left pages to read = 350 - 270 = 80

Hence The number of pages left to read after 10 days is 80 . Answer

Answer 2

She will still have 80 pages left to read after 10 days.

Explanation:

Keisha is reading the book at a rate of 27 pages per day. The book has 350 pages. So , after x days , the no. of pages remaining to read is,

`y = 350 - 27 * x` ---------------(1)

Here, the given value of x is 10. So, putting x = 10 in (1) we get,

`y = 350 - 27 * 10`

= 80
