Let x be the larger number; Let y be the smaller number.
EQUATIONS:
x-2y=1
x+y+20=3x
---------
Rewrite as
x-2y=1

Multiply the 1st equation by 2 to get:
2x-4y=2
Subtract this result from the 1st equation to get:
3y=18
y=6
Substitute that into the 1st equation to get:
x-2*6=1
x=13
-------
Solution: x=13; y=6
The number of times Ken visits, given the £3.6 pool charge, and 1/3 savings per visit is 5 times.
<h3>Which method can be used to find the number of times Ken visits the pool to get back his £5?</h3>
The entry fee = £3.60
Amount saved on entry fee by having a membership card = 1/3 of the entry fee
Amount Ken spends on the membership card and the reduced entry fee = £5
Therefore;
Reduced entry fee = £3.60×(1 - 1/3) = £2.4
Amount saved per visit = £3.6 - £2.4 = £1.2
The number of visits, <em>n</em>, before he gets back his £5 is therefore;
- n = £5/(£1.2/visit) ≈ 4.17 visits
Ken has to visit the swimming pool more than 4 times to get his £5 back.
Rounding to the next larger whole, therefore;
- The number of visits, n, before he gets back his £5 is 5 visits
