Answer

$c \leq .1*(m-500)+25$ $550 \leq m$ 27.50 for 525 minutes

Work Step by Step

$c \leq .1*(m-500)+25$ $30 \leq .1*(m-500)+25$ $30-25 \leq .1*(m-500)+25-25$ $5 \leq .1*(m-500)$ $5*10 \leq 10*.1*(m-500)$ $50 \leq m-500$ $50+500 \leq m-500+500$ $550 \leq m$ $c \leq .1*(m-500)+25$ $c \leq .1*(525-500)+25$ $c \leq .1*(25)+25$ $c \leq 2.5+25$ $c = 27.5$
