Problem 9
Gone Swimming
Cody and Jimmy spent lots
of time at Ellsworth’s new swimming pool.
Cody purchases single day passes for $1.50/day. Jimmy bought a year pass for $200.00. If both boys swim 120 days which got the better
deal? By how much?
Solution:
120 Days $200.00 Jimmy’s cost
x1.50 -180.00
Cody’s cost
$180.00 Cody’s cost for
120 days $ 20.00 Cody’s loss
Jimmy would pay $20.00 more for 120 days of
swimming.
If both boys swam 175 days would the person
who gets the better deal change?
Solution:
Yes Jim would then get the better deal. Cody will spend $62.50 more than Jim pays
for a years pass.
175
x$1.50
$262.50 Cody’s cost
