Question

A community pool charges $78 for swim lessons and a $2 towel rental fee per day. At the end of the summer Yolanda spends $102. How many days did Yolanda go for swim lessons?

Answer 1

Answer: 12 days

Explanation:

Given

A community pool charges $78 for a swim lesson and $2 for a towel each day

Suppose Yolanda attended the session for x days

So, we can write the total fees of $102 as

`\Rightarrow 102=78+2x\\\Rightarrow 2x=102-78\\\\\Rightarrow x=(24)/(2)\\\\\Rightarrow x=12`

So, Yolanda attended the swim lessons for 12 days
