Marla swims twice a week. Her equipment cost her $32.25 and she has a membership to the pool for $35 plus $3.50 per visit. She can walk to the pool, so transportation is free. How much will swimming cost her for the year?

    Total cost = pool equipment cost + membership fee + (cost per week) (no. weeks) Suppose that x = no. of weeks Total cost = 32.25 + 35 + 2*3.50*12
