Mika talks with two different companies about having a banner printed.

--The first company uses the equation c = 2.75f + 75 to determine the cost, c, in dollars, for a banner with an area of f square feet.

• The cost at the first company is always less than the cost at the second company for banners with equal area.

• The cost at the second company is always less than the cost at the first company for banners with equal area.

• The cost at the first company is less than the cost at the second company for banners with an area less than a particular value.

• The cost at the second company is less than the cost at the first company for banners with an area less than a particular value.
