Source Natural Home and Garden CHECK POINT 5 Being aware of which appliances and activities inyour home use the most energy can help you make sound decisions thatallow you to decrease energy consumption and increase savings. Thecircle graph in Figure 1.4 shows how energy consumption is distributedthroughout a typical home. Suppose that last year your family spent $2148.72 on natural gas andelectricity. Assuming the circle graph in Figure 1.4 is representative ofyour family’s energy consumption. a. Use the appropriate information displayed by the graph todetermine a calculation that shows the amount your family spenton heating and cooling for the year. 0.48 × 24.48.72 b. Use rounding to find a reasonable estimate for this calculation. 0.5 × 2100 = 1050 Your family spent approximately $1050 on heeling end cooling lost year.
