Answer:
Cost of Television = $294
Step-by-step explanation:
7% discount means 7/100 = 0.07 LESS
So we need to multiply by 1 - 0.07 = 0.93
Also, 10% MORE, or extra, means 10/100 = 0.10 MORE
So we need to multiply by 1 + 0.10 = 1.1
Let cost of television be "c", so we can say:
- 7% discount would mean cost to be c(0.93) = 0.93c
- 10% with interest would mean cost to be c(1.10) = 1.10c
The difference is 49.98. So we subtract lower value (0.93c) from larger value (1.10c) and equate to 49.98 and solve for c:

Answer:
Step-by-step explanation:
Given the mass M(a decreasing function) of a sample of a radioactive element at time t.
The rate of change of the sample’s mass , is proportional to the mass, M of the sample.
This is written as:
Introducing the decay constant k,
This is the equation which model the relationship between the mass of the sample and the rate of change of the sample’s mass.
The other options are therefore invalid.
