To find the cost per week, divide the total cost by how many weeks you are signing up for.
Total cost / number of weeks = cost per week
$325 / 13 weeks = $25 per week
The cost per week is $25 for swimming lessons.

Answer:
140
Step-by-step explanation:
we know that this year the sports club has 25% less memeber, so if last year the members where 100% this year there are only 75%
and that 75% is equal to 105 members
we can represent the information that we are given in a table:
memebers percentage
105 ⇒ 75%
since last summer there were the 100% of member we can represent the number of members from last summer with 'x', and the table now is:
memebers percentage
105 ⇒ 75%
x ⇒ 100%
and we use rule of three to solve this problem: multiply cross quantities (105 by 100) and divide by the remaining amount:
x = 105*100/75
x = 140
Last summer the sports club had 140 members
