Answer: 9.24
Step-by-step explanation:
4.9+ -1.2(0.7)- - 5.18
+ + = +
+ - = - + = -
- - = +
Therefore:
4.9+ -1.2(0.7)- - 5.18 = 4.9 - 1.2*(0.7) + 5.18 =4.9 - 0.84 + 5.18 = 9.24
The current salary is <span> $44,200. In this case, the percent increase is 4%. The percent increase serves like an investment in which the interest is compounded. The formula that applies here is current = previous *( 1.04)^n where n is 1. Last year's salary is $42,500</span>
Suppose s and h are the mileage numbers for the SUV and Hybrid, respectively. Then if each vehicle drives 1 mile, the total gas consumption is
.. 1/s +1/h
Then the combined mileage is
.. 2/(1/s +1/h) = 2sh/(s+h)
Option 1: s=12, h=60
.. mpg = 2*12*60/(12+60) = 20
Option 2: s=11, h=75
.. mpg = 2*11*75/(11 +75) = 1650/86 ≈ 19.2
In summary,
.. Option 1: 20.0 mpg
.. Option 2: 19.2 mpg
