Strawberries are on sale for $0.75 a pound, and you have a coupon for $0.40 off your total purchase. Write a function rule for the cost of n
pounds. How much would 20 pounds of strawberries cost? (1 point)
y=0.75x ; $15
y= 0.75x - 0.40 ; $14.60
The correct function rule for the cost of n pounds of strawberries is y = 0.75n - 0.40.
To find how much 20 pounds of strawberries would cost, we can substitute n = 20 into the function.
y = 0.75(20) - 0.40
y = 15 - 0.40
y = 14.60
Therefore, 20 pounds of strawberries would cost $14.60.
