Question

You are selling doughnuts at different rates. A customer purchases 11 doughnuts for $1.15 each. If the customer purchases a dozen doughnuts, it is$10. Extra doughnuts after that are $0.75 each.Let y represent the cost to the customer and x represents the number of doughnuts the customer purchases.Select the equations that represent the constraints that apply to the situation.

Answer 1

11 doughnuts for $1.15 each

12 doughnuts for $10

extra donuts after that: $0.75 each

x = each donut (after 12)

So, the cost is:

y = 10+0.75x when x≥12

Also

y= 1.15x when x<12
