Print the following on a piece of paper, then work out each question.
Solve the following:

1) While exercising in the morning I burn 0.124 calories per stride. How many strides would I need to take to burn at least 500 calories (round to the nearest stride).

x = number of strides
.0124 x = 500
x = 4032.3

Strides = 4032 or 4033

2)To save money YVCC keeps the buildings at 71 degree F. Convert this to Celsius. Use $\displaystyle {F}={\left(\frac{{9}}{{5}}\right)}{C}+{32}$ for the conversion between degrees Fahrenheit and degrees Celsius. Round to 1 decimal place.
$\displaystyle {F}={\left(\frac{{9}}{{5}}\right)}{C}+{32}$
$\displaystyle {71}={\left(\frac{{9}}{{5}}\right)}{C}+{32}$
$\displaystyle {39}={\left(\frac{{9}}{{5}}\right)}{C}$

$\displaystyle {21.6666}\ldots={C}$

$\displaystyle {C}={21.7}$
