Question

Danny charges $20 for 2 hours of swimming lessons, Martin charges $68 for 4 hours of swimming lessons. Who offers a better deal

Answer 1

Danny’s rate for 2 hours of lessons is $20...or $10 per hour (20/2=10).
Martin’s rate is $17 per hour (68/4=17).
So Danny’s rate per hour is much cheaper, that is the better deal.

Answer 2

Danny

Explanation:

Its quite obvious really.

Multiply Danny's charges by 2

20 x 2

Thats $40 for 4 hours unlike Martins $68 for 4 hours.

If you wanna go further,

Minus Martins charges with Dannys

68 - 40

Thats a $28 gap.
