1

Step-by-step explanation:

2-(5 to the 8th power/5 to the 8th power)

= 2 - (5^8 - 5^8)

= 2 - 5^(8-8)

= 2 - 5^0

= 2 - 1

= 1

Part A:

c = .86*p

c =1.72 for 2 lbs

Part B:

c =.81p

Step-by-step explanation:

Part A:

Total cost = cost per pound * number of pounds

c = .86*p

Let p = 2

c = .86*2

c =1.72

Part B:

Total cost = cost per pound * number of pounds

c = .(.86-.05)*p

c =.81p
