Question

A pass to a water park is $58. A discount of 10% is given to customers at the end of the season.

Answer 1

Answer: $52.20

Steps:
First way:
10% = 0.1
$58 x 0.1 = $5.80
$58 - $5.8 = $52.20

Second way:
100% = 1
10% = 0.1
1 - 0.1 = .9
That means that when the 10% is taken off, 90% still has to be paid.
$58 x 0.9 = $52.20
