Answer:
C
Step-by-step explanation:
Do u still have this homework or is it old
Let c=cost of cherry and s=cost of strawberry cheesecakes.
12c+14s=214
6c+11s=151.
So 12c+22s=302 subtract 12c+14s=214:
8s=88, so s=$11 and 6c=151-11s=151-121=$30.
The cost of one cherry cheesecake is $30 and of one strawberry is $11.
The cost of the sum of both is $41.
A. This is true. If 0 < r < 1, then we have decay. For example, if r = 0.5 then we cut each term in half to get successive new terms (10, 5, 2.5, 1.25, etc etc)
B. False. Common differences apply to arithmetic sequences which are not exponential in nature.
C. False. Decay curves slope downward. As you read them from left to right, they will drop down.
D. False. If r > 1, then we have exponential growth. It is effectively the opposite of choice A.
