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, $
y=0.75x-0.40, $14.60
y=(0.75-0.40)x. $7
y=0.4x-0.75 $7:25
The correct function rule for the cost of n pounds of strawberries is:
y = 0.75n - 0.40
To find the cost of 20 pounds of strawberries, substitute n = 20 into the function:
y = 0.75(20) - 0.40 = 15 - 0.40 = $14.60
Therefore, 20 pounds of strawberries would cost $14.60.
