Suppose yogurt is on sale for $0.50 a piece and you have a coupon for $0.30 off your total order. Write a function rule for the cost of n yogurts. How much would 20 yogurts cost? (1 point) * C(n) = 0.5n – 0.3; $9.70 * C(n) = 0.3n – 0.5; $5.50 * C(n) = 0.3n; $4.00 * C(n) = 0.5n; $10.00

C(n) = 0.5n - 0.3: $9.70
