Okay so the first thing we are going to do is change 
into a improper fraction: 
.
=224÷25=8.96
as a decimal is 
.
Using linear functions, it is found that:
- Jose's equation is:
.
- Gavin's equation is:
.
- They will be on the same page on the 9th day.
A <em>linear function</em> is modeled by:
In which:
- m is the slope, which is the rate of change.
- b is the y-intercept, which is the value of y when x = 0.
Jose:
- Initially, he was on page 10, hence
.
- He reads 17 pages per day, hence
.
- Hence, Jose's equation is:
Gavin:
- Initially, he was on page 37, hence
.
- He reads 14 pages per day, hence
.
- Hence, Gavin's equation is:
The day they will both be on the same page is x for which:
Hence:
They will be on the same page on the 9th day.

Answer
Find out the how much did kerry pay in tax .
To proof
As given
Kerry bought a bag of dog food for $37.99.
If sales tax is 7.6%
7.6 % is written in the decimal form
= 0.076
7.6 % of the $37.99 = 0.076 ×37.99
= 2.88724
= $2.89 ( approx)
Kerry pay in the sales tax be $2.89
Hence proved
