The total cost, c, in dollars for the use of a catering service can be found using the function c = 5.25s + 45.50, where s is the number of people served. If the number of people served at the event will be at least 195 but cannot exceed 200, what is a reasonable range for this situation?

• 0 ≤ s ≤ 200

• {1069.25, 1074.50, 1079.75, 1085, 1090.25, 1095.50}

• 45.50 < c ≤ 1,045

• {195, 196, 197, 198, 199, 200}
