Answer:

Step-by-step explanation:

Giving the following information:

Bernie's Bargains 6 DVDs for $56.70

Greg's Giveaways 10 DVDs for $99.70

Stan's Steals 8 DVDs for $79.68

First, we need to determine the unitary price of each and choose the lowest one:

Bernie= 56.7/6= $9.45

Greg= 99.7/10= $9.7

Stan= 79.68/8= $9.96

The lowest price is $9.45.

Now, the total cost of 15 DVDs:

Total cost= 9.45*15

Total cost= $141.75

b) The regular price of the pastry bought by Kimberly = $2.70

Step-by-step explanation:

0.75x = 2.03

x = $\frac{2.03}{0.75}$ = 2.70

Regular price of the pastry bought by Kimberly = $2.70
