Answer:
50 pack

Step-by-step explanation:
Number of packs at Costco = 30
Cost of 30 packs at Costco = $10.82
Number of packs at the other place = 50
Cost of 50 packs = $17.25
Cost of one pack when 30 packs are bought

Cost of one pack when 50 packs are bought

It is better to buy the 50 pack.
Difference in the unit prices =
.
Ok so d is across from angle 70, thiat means that are equal, so d=70
then you can easily tell angle e is 180 - d, Wich is 110, so angle e is 110
angle a plus angle 70 is 90 degrees, so 90-70=20, so angle a is 20
it says angle b plus angle a is 90, we know angle a is 20, so 20plus 70 equals 90, so angle b is 70 degrees
angle b plus angle c equals 90, so we know b is 70. that makes angle c 20
