Work: Calculate the value of equation 7.191+(38.9+8/4×2)×(1+7%)×(1+9%)×85%-10.022 .
Question type: Mathematical calculation
Solution:
7.191+(38.9+8/4×2)×(1+7%)×(1+9%)×85%-10.022
=7.191+42.9×(1+7%)×(1+9%)×85%-10.022
=7.191+42.9×1.07×(1+9%)×85%-10.022
=7.191+42.9×1.07×1.09×85%-10.022
=7.191+42.9×1.07×1.09×0.85-10.022
=7.191+45.903×1.09×0.85-10.022
=7.191+50.03427×0.85-10.022
=7.191+42.529129-10.022
=49.720129-10.022
=39.698129
Answer:7.191+(38.9+8/4×2)×(1+7%)×(1+9%)×85%-10.022=39.698129
