Question

How much do you save per class by taking the longer-term class: Weight Training, $200 for 18 weeks (54 classes) or $350 for 36 weeks (108 classes)?

Answer 1

Shorter term class:

You pay $200 for 54 classes in total. So,

$\frac{200}{54} =3.704$ dollars per class (rounded to 3 decimal places)

Longer term class:

You pay $350 for 108 classes in total, So,

$\frac{350}{108} =3.241$ dollars per class (rounded to 3 decimal places)

Hence, by taking longer term classes, you save around $3.704-3.241=0.463$ dollars.

Rounding to 2 decimal places, you save $0.46 per class.

ANSWER: You save $0.46 per class.

Answer 2

It's $200 divided in to 54 = $3.70
Then $350 divided in to 108=
$3.24
Then just subtract $3.70 - $3.24 = 46¢ per class
Hope I helped :)
