So the watch costs 75.99 including sales tax.
The sales tax is 6.25% of the value of the watch.
100% of the value of the watch is n.
100% + 6.25% of the value of the watch is 106.25/100 * n = 75.99
Let's calculate the sales tax...

Answer:
1. The equations is inconsistent and has no solution
2. The equations is consistent and has no solution
3. A pen costs $1.50 and a notebook costs $2.00
Step-by-step explanation:
Solving and
--- Equation 1
--- Equation 2
Add 7x to both sides in equation 2
--- Equation 3
Subtract equation 3 from 1
The equations is inconsistent and has no solution
Solving and
-- Equation 1
---- Equation 2
Make y the subject of formula in equation 1
Substitute 4 - 3x for y in equation 2

3. Solving <em>John and Harry</em>
Given;
<em>Represent Pen with P and Notes with N</em>
John:
Harry:
Required
Find P and N
Make P the subject of formula in equation 2
Substitute in equation 1
Open the bracket
Take LCM
Multiply both sides by 4
Subtract 48 from both sides
Divide both sides by 17
Substitute 2 for N in
