Soda is on sale for 0.75 a can, you have a coupon for 0.50 off your total purchase write a function rule for the cost of n sodas. How much would 10 sodas cost

Answer 1

The function rule for the cost of n sodas is: Cost(n) = (0.75 * n) - 0.50
To find out how much 10 sodas would cost, we can substitute n = 10 into the function rule:
Cost(10) = (0.75 * 10) - 0.50
Cost(10) = 7.50 - 0.50
Cost(10) = $7
Therefore, 10 sodas would cost $7.
