Answer: The cycle can be purchased for $462 
Explanation:
Hi, to answer this question, first, we have to calculate the amount of the sales tax by multiplying the price of a bicycle (420) by the sale tax percentage in decimal form (10/100=0.1) 
Mathematically speaking: 
420 x 0.1 = $42 
Finally, we have to add the sale tax amount to the price of the bicycle. 
420+42 = $462 
The cycle can be purchased for $462
