You should start off by modelling this question. First start off with saying how many 30 minute appointments he can make and how many 45 minute appointments he can make. See where you can go from there.

$x=$x= Number of 30-minutes $\left(\frac{1}{2}hour\right)$(12 hour) appointments

$y=$y= Number of 45-minutes  $\left(\frac{3}{4}hour\right)$(34 hour) appointments

$\left(\frac{1}{2}\right)x+\left(\frac{3}{4}\right)y\le30$(12 )x+(34 )y30

Let x be the number of 30 minute appointments (0.5x) Let y be the number of 45 minute appointments (0.75y) By adding these together you get an inequality that shows you the possible combinations that Gary can make in a week. Thus the equation becomes: 0.5x + 0.75y ≤ 30 (in hours)

For an equation in minutes, you multiply each value used by 60 and thus the equation becomes: 30x + 45y ≤ 1800

30x+45y 1800 (minutes)

0.5x+0.75y 30 (hours)
