Answer 2

Greetings!

"Ika borrowed a book from the library and forgot to return it on time. the library charges 0.25 per day for the first four days ...how many days late was her book?"

This can be solved by creating an algebraic equation:

`0.25(4)+0.30x=4`

Solve for x:

`0.25(4)+0.30x=4`
Simplify.

`1+0.30x=4`
Add -1 to both sides.

`(1+0.30x)+(-1)=(4)+(-1)`
Simplify.

`0.30x=3`
Divide both sides by 0.30.

`(0.30x)/0.30=(3)/0.30`
Simplify.

`x=10`

10+4=14

She was 14 days late on returning her book.

Hope this helps.
