Answer:

I would say that Danny's deal is better.

Step-by-step explanation

If you wan t to know the better deal you should first figure out how much they charge per hour. All you have to do is divide the price by the amount of hours.

Danny: 44 ÷ 4 = 11

Martin: 42 ÷ 3 = 14

Martin charges more money for fewer hours. Danny charges less for 4 whole hours, so he would be the better deal!!!
