Answer:
Step-by-step explanation:
1 sandwich is 6.25 (because 31.25/5)
2 sandwiches is 12.5
3 sandwiches are 18.75
4 sandwiches are 25
5 sandwiches are 31.25
6 sandwiches are 37.5
Amy - 8s + 12
8(6.25) +12 = 62
Amy paid $62.
Bob - 8(s + 2)
8(6.25 + 2) = 66
Bob pays $66.
Cathy - 4(2s + 3)
4(2 x 6.25 + 3) = 62
Cathy paid $62.
The answer is x= 1/5 or 0.2
Answer: a) , where 'A' is the value of car after 't' years.
b) $12446.784
Step-by-step explanation:
Given: A new car that sells for $21,000 depreciates (decreases in value) 16% each year.
Then a function that models the value of the car will be
, where 'P' is the selling price of car, 'r' is the rate of depreciation in decimal, 't' is the time in years and 'A' is the value of car after 't' years.
Thus after substituting given value, the function becomes
To find the value after 3 years, substitute t=3 in the above function.
Hence the value of car after 3 years=$12446.784
