John rents a booth for $35.00 a day and sells ice cream cones.
\n" ); document.write( "His cost for each cone is $2.00 and he sells the cones for $5.00 each.
\n" ); document.write( "If John wants to make at least a $200.00 profit for the day, how many ice cream cones must he sell?\r
\n" ); document.write( "\n" ); document.write( "a. 34\r
\n" ); document.write( "\n" ); document.write( "b. 78\r
\n" ); document.write( "\n" ); document.write( "c. 79\r

\n" ); document.write( "\n" ); document.write( "Remember that: Revenues – cost = profit \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let the amount of ice cream cones he has to sell to make a $200 profit be C
\n" ); document.write( "Then the cost of the cones he hopes to sell = 2C, and his total costs are: 2C + $35\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "His revenues from selling C ice cream cones, at $5 per cone = 5C\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We now have:

\n" ); document.write( "\n" ); document.write( "Since we don’t have fractional amounts of ice cream cones, we round up this amount to 79\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This means that in order for him to make a $200 profit for the day, he has to sell AT LEAST \"highlight_green%2879%29\" ice cream cones (CHOICE C)\r
