In September, a sporting goods store offers a kayak for $378.  Over the next four months, the store reduced the price of the kayak $15 each month.  What is the price of the kayak at the end of four months?

1 answer

The kayak is reduced by $15 each month for four months so 4*15 = $<<15*4=60>>60 discount
The kayak is $378 and it receives a $60 discount so it costs 378-60 = $<<378-60=318>>318. Answer: \boxed{318}.
