Work: Calculate the value of equation 230*0.3+240*0.2+250*0.15+260*0.15+27+280*0.05+290*0.05 .
Question type: Mathematical calculation
Solution:
230*0.3+240*0.2+250*0.15+260*0.15+27+280*0.05+290*0.05
=69+240*0.2+250*0.15+260*0.15+27+280*0.05+290*0.05
=69+48+250*0.15+260*0.15+27+280*0.05+290*0.05
=69+48+37.5+260*0.15+27+280*0.05+290*0.05
=69+48+37.5+39+27+280*0.05+290*0.05
=69+48+37.5+39+27+14+290*0.05
=69+48+37.5+39+27+14+14.5
=117+37.5+39+27+14+14.5
=154.5+39+27+14+14.5
=193.5+27+14+14.5
=220.5+14+14.5
=234.5+14.5
=249
Answer:230*0.3+240*0.2+250*0.15+260*0.15+27+280*0.05+290*0.05=249
