Answer
a. $C=5500+1500+0.45(x)$
b. 8350 dollars
c. 8000 snow cones
Work Step by Step
a. C=cost of selling snow cones, x=number of snow cones sold
$C=5500+1500+0.45(x)$
b. x=3000
$C=7000+0.45(3000)$
$C=7000+1350$
$C=8350$
c. $C=10,600$
$10,600=7000+0.45(x)$
$10,600-7000=0.45(x)$
$3600=0.45(x)$
$3600\div0.45=x$
$x=8000$
