Answer:
f(x) = -1.25x + 64 I hope this helps :)
Explanation:
total amount of money: $80
He spent $16 for the entrance of the fair and food.
80-(4+12) = 64
After that you subtract $1.25 per ride = -1.25x
Then it gives the function:
f(x) = -1.25x + 64
You enforce the rules, state you did correctly count the amount of money, no exceptions.
Answer:
differential cost of producing product C = $24 per pound
Explanation:
given data
B currently selling = $30 per pound
produce cost = $28 per pound
C would sell = $60 per pound
produce additional cost = $24 per pound
to find out
What is the differential cost of producing Product C
solution
we get differential cost of producing product C is express as
differential cost of producing product C = cost of (B+C) - cost of B .............1
put here value we get
differential cost of producing product C = (28+24) - 28
differential cost of producing product C = $24 per pound
Answer:
10.29%
Explanation:
Rule of 72 can be defined as a metric used to determine the time it will take to double an investment based on its growth rate.
To find the interest rate Kari must receive for her investment to double in 7 years, we would use the Rule of 72;
Rule of 72 = 72/7
Rule of 72 = 10.29%
Therefore, Kari must receive an interest rate of 10.29% for her investment to double in 7 years.
