Bryce has heard that gas appliances are cheaper to use and can lower utility costs. He is interested in purchasing a new gas sto
ve for his kitchen to replace his electric stove. Assuming that the stove gets used one hour per day, use the following chart to determine how much Bryce will save each month in utility costs by purchasing the gas appliance. (Assume 30 days per month.)
Electric Stove 13 cents per hour
Gas Stove
5 cents per hour
A $3.90
B. $1.50
c. $2.40
D$4.30
20% discount makes the price $58. Sales tax brings this to $61.77. On the website the cost is 54.75×1.09+5.99=$65.6675 for each pair. The difference is exactly $3.8975 or $3.90 if working to the nearest cent. For 12 pairs the difference in cost is $46.77 or $46.80 respectively.
