For the month of January, the average afternoon temperature in Calgary is 1/4 the average morning temperature. The average afternoon temperature is -4 C. If "m" represents the average morning temperature, what equation models this problem?
If m=average morning temperature, then the average afternoon temperature is 1/4m, or:
m=1/4m. But, since the average afternoon temperature is -4, then the average morning temperature would be:
1/4m=-4 divide both sides by 1/4
m= -4 / (1/4)=-4 x 4
m=-16C - average morning temperature in Calgary.
