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?
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}.
To find the final price of the kayak after four months, we need to subtract $15 for each of the four months from the original price of $378.
$378 - ($15 x 4) = $378 - $60 = $318
So, the price of the kayak at the end of four months is $318.
