For delivery orders, customers must order at least two dozen donuts. The first two dozen donuts cost $5.99 each. Any additional donuts ordered cost $4.99 per dozen.

If x represents the number of additional dozens of donuts, which of the following equations can be used to find the cost of the order, not including tax or a delivery charge? A. y = 4.99x + 5.99
B. y = 5.99x + 4.99
C. y = 11.98x + 4.99
D. y = 4.99x + 11.98

since you need to order at least 2 dozens, therefore you'll be having the first price multiplied by two.. 5.99(2)
since additional costs 4.99 then let x be the number of additional dozens of donuts
making the equation
y= 4.99x + 5.99(2)
