To calculate the new wage, start off by multiplying $8.15 0.07 = $0.57. Then add that number (the amount of Joe's raise) to his original hourly wage. Joe's new hourly wage is $8.15 + $0.57 = $8.72.

The fivemajorlayers of the atmosphere from the Earth's surface upward are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Thetropospherestarts at the Earth's surface and extends to between 23,000 ft (7 km) at the poles and 60,000 ft (17 km) at the equator, with some variations due to weather factors. Thestratosphereextends from the top of the troposphere (23,000- 60,000 ft or 7-17 km) to about 160,000 ft (60 km). Thestratospherecontains theozone layer,which is mainly located in the lower part of the stratosphere from about 50,000-115,000 ft (15-35 km) above the surface, although the thickness varies somewhat across both the seasons and the Earth's geographical regions. Themesosphereextends from about 160,000 ft (50 km) to about 265,000-285,000 ft (50-54 miles or 80-85 km). This is also where most meteors bum up when entering the atmosphere
