A high school club is researching a tour package offered by the Island Kayak Company. The Company charges $35 per person and $245 for the tour guide. Which function represents the total cost, C (x), of this kayak tour package for x club members?

• C(x) = 35x

• C(x) - 35x + 245

• C(x) = 35(x + 245)

• C(x) = 35 + (x +245)

An ice cream shop sells ice cream cones, c, and milkshakes, m. Each ice cream cone costs $1.50 and each milkshake costs $2.00. Donna has $19.00 to spend on ice cream cones and milkshakes. If she must buy 5 ice cream cones, which inequality could be used to determine the maximum number of milkshakes she can buy?

• 1.50(5) + 2.00(m) > 19.00

• 1.50(5) + 2.00m < 19.00

• 1.50c + 2.00(5) > 19.00

• 1.50c + 2.00(5) < 19.00
