A pen costs $2.09. it costs $0.45 less than a marker. Ken paid for one pen and one marker. How much money did ken spend on the pen and marker?

Cost of the pen: The pen costs $2.09.

Cost of the marker: Since the pen costs $0.45 less than the marker, we add $0.45 to the price of the pen to find the cost of the marker:

Cost of the marker= 2.09+0.45= 2.54

 Total cost for both items: To find how much Ken spent on the pen and the marker, add the cost of the pen and the cost of the marker: 

Total cost= 2.09 + 2.54=4.63
