Answer:

the first machine would cost $420 and the second machine would cost $432

Joanne, you should buy the first machine

Step-by-step explanation:

If you get a 30% discount, then you are paying 70% of the selling price. Machine 1:  600(.70) = 420 Machine 2:  A 10% discount means you pay 90% 600(.90) = 540   But now you get a 20% discount on that amount, which means you would pay 80% So, 540(.80) = 432 Therefore, the first machine would cost $420 and the second machine would cost $432
